A shunt resistance-type current sensor comprising: a busbar shaped into an approximately flat plate; a circuit board opposed to the busbar; a pair of voltage detection terminals (41, 42) that are integrally formed with the busbar and electrically connect the busbar and the circuit board; a voltage detector that is provided on the circuit board and detects a voltage applied to the circuit board through the pair of voltage detection terminals (41, 42) to detect a magnitude of a measurement subject current flowing through the busbar; and a temperature detector that is provided on the circuit board and detects a temperature of the busbar to allow the voltage detector to conduct a correction, characterized by the fact that each of the voltage detection terminals (41, 42) comprises: a first bent portion in which a portion extending from a side edge portion of the busbar is bent to such a direction as to go away from the circuit board; a second bent portion in which a portion extending from the first bent portion is bent toward the circuit board, said second bent portion being located at a position that is more distant from the circuit board than in the absence of such a first bent portion so that the clearance between the busbar and the circuit board is reduced; and a connection portion which extends straightly from the second bent portion and has a tip portion that has been subjected to tapering for thickness reduction; by the fact that the tip portions of the connection portions of the voltage detection terminals (41, 42) penetrate through the circuit board and the voltage detection terminals (41, 42) are thereby electrically connected to the circuit board; by the fact that the first bent portion is formed at a position that is immediately adjacent to the position at which said portion extends from the busbar, by the fact that bending is made in the first bent portion so that a portion extending from the first bent portion extends parallel with the busbar; and by the fact that the portion extending from the first bent portion in the second bent portion is bent by about 90° toward the circuit board at a position corresponding to the circuit board. a busbar shaped into an approximately flat plate; a circuit board opposed to the busbar; a pair of voltage detection terminals (41, 42) that are integrally formed with the busbar and electrically connect the busbar and the circuit board; a voltage detector that is provided on the circuit board and detects a voltage applied to the circuit board through the pair of voltage detection terminals (41, 42) to detect a magnitude of a measurement subject current flowing through the busbar; and a temperature detector that is provided on the circuit board and detects a temperature of the busbar to allow the voltage detector to conduct a correction, characterized by the fact that each of the voltage detection terminals (41, 42) comprises: a first bent portion in which a portion extending from a side edge portion of the busbar is bent to such a direction as to go away from the circuit board; a second bent portion in which a portion extending from the first bent portion is bent toward the circuit board, said second bent portion being located at a position that is more distant from the circuit board than in the absence of such a first bent portion so that the clearance between the busbar and the circuit board is reduced; and a connection portion which extends straightly from the second bent portion and has a tip portion that has been subjected to tapering for thickness reduction; a first bent portion in which a portion extending from a side edge portion of the busbar is bent to such a direction as to go away from the circuit board; a second bent portion in which a portion extending from the first bent portion is bent toward the circuit board, said second bent portion being located at a position that is more distant from the circuit board than in the absence of such a first bent portion so that the clearance between the busbar and the circuit board is reduced; and a connection portion which extends straightly from the second bent portion and has a tip portion that has been subjected to tapering for thickness reduction; by the fact that the tip portions of the connection portions of the voltage detection terminals (41, 42) penetrate through the circuit board and the voltage detection terminals (41, 42) are thereby electrically connected to the circuit board; by the fact that the first bent portion is formed at a position that is immediately adjacent to the position at which said portion extends from the busbar, by the fact that bending is made in the first bent portion so that a portion extending from the first bent portion extends parallel with the busbar; and by the fact that the portion extending from the first bent portion in the second bent portion is bent by about 90° toward the circuit board at a position corresponding to the circuit board.
