A straddled electric vehicle, comprising: at least one steerable wheel; at least one driving wheel; a steering mechanism for steering the at least one steerable wheel in response to operation by a rider; a battery; a power unit including an electric motor which is supplied with power from the battery to generate driving force, the power unit being adapted to rotate the at least one driving wheel with the driving force generated by the electric motor; a control apparatus including a control circuit and a heat sink, wherein the control circuit controls the electric motor, and the heat sink is in contact with the control circuit to dissipate heat generated by the control circuit; and a vehicle body, wherein the vehicle body supports the at least one steerable wheel, the at least one driving wheel, the steering mechanism, the battery, the power unit, and the control apparatus, the vehicle body includes a vehicle-body left part which is a portion located to the left of a center of the vehicle body in a vehicle-body left-right direction, and a vehicle-body right part which is a portion located to the right of the center of the vehicle body in the vehicle-body left-right direction, and the vehicle body forms a vehicle body space (Sp) extending in a vehicle-body front-back direction between the vehicle-body left part and the vehicle-body right part, wherein the vehicle body has a structure in which the heat sink which dissipates the heat generated when the control circuit controls the electric motor is secured to both the vehicle-body left part and the vehicle-body right part such that at least a part of the control circuit is located in the vehicle body space (Sp) which is formed so as to extend in the vehicle-body front-back direction between the vehicle-body left part and the vehicle-body right part, wherein the vehicle body includes a vehicle body opening, which is located between the vehicle-body left part and the vehicle-body right part as seen in the vehicle-body downward direction, and which connects the inside of the vehicle body space (Sp) and the outside of the vehicle body space (Sp), wherein the battery is disposed in the vehicle body space (Sp), wherein the heat sink is secured to a rear end of the vehicle-body left part and a rear end of the vehicle-body right part so as to function as a reinforcing member for restricting the vehicle body from deforming in such a way that the spacing between the vehicle-body left part and the vehicle-body right part changes, and so as to be overlapped with the vehicle body space (Sp) as seen in the vehicle-body frontward direction, characterized in that the control circuit is located on a front face of the heat sink and the heat sink is attached behind the control circuit in the vehicle-body backward direction (b). at least one steerable wheel; at least one driving wheel; a steering mechanism for steering the at least one steerable wheel in response to operation by a rider; a battery; a power unit including an electric motor which is supplied with power from the battery to generate driving force, the power unit being adapted to rotate the at least one driving wheel with the driving force generated by the electric motor; a control apparatus including a control circuit and a heat sink, wherein the control circuit controls the electric motor, and the heat sink is in contact with the control circuit to dissipate heat generated by the control circuit; and a vehicle body, wherein the vehicle body supports the at least one steerable wheel, the at least one driving wheel, the steering mechanism, the battery, the power unit, and the control apparatus, the vehicle body includes a vehicle-body left part which is a portion located to the left of a center of the vehicle body in a vehicle-body left-right direction, and a vehicle-body right part which is a portion located to the right of the center of the vehicle body in the vehicle-body left-right direction, and the vehicle body forms a vehicle body space (Sp) extending in a vehicle-body front-back direction between the vehicle-body left part and the vehicle-body right part, wherein the vehicle body has a structure in which the heat sink which dissipates the heat generated when the control circuit controls the electric motor is secured to both the vehicle-body left part and the vehicle-body right part such that at least a part of the control circuit is located in the vehicle body space (Sp) which is formed so as to extend in the vehicle-body front-back direction between the vehicle-body left part and the vehicle-body right part, wherein the vehicle body includes a vehicle body opening, which is located between the vehicle-body left part and the vehicle-body right part as seen in the vehicle-body downward direction, and which connects the inside of the vehicle body space (Sp) and the outside of the vehicle body space (Sp), wherein the battery is disposed in the vehicle body space (Sp), wherein the heat sink is secured to a rear end of the vehicle-body left part and a rear end of the vehicle-body right part so as to function as a reinforcing member for restricting the vehicle body from deforming in such a way that the spacing between the vehicle-body left part and the vehicle-body right part changes, and so as to be overlapped with the vehicle body space (Sp) as seen in the vehicle-body frontward direction, characterized in that the control circuit is located on a front face of the heat sink and the heat sink is attached behind the control circuit in the vehicle-body backward direction (b).
