Claim Text:
1. A photosensor comprising: a light emitter; a light receiver configured to receive light from the light emitter and output a light receiving signal; a circuit-encapsulating portion encapsulating an integrated circuit that processes the light receiving signal; a connecting terminal protruding from the circuit-encapsulating portion, the connecting terminal being configured to connect to an external terminal; a first emitter lead and a second emitter lead configured to connect the light emitter and the circuit-encapsulating portion, the emitter leads being flat plates; and a first receiver lead and a second receiver lead configured to connect the light receiver and the circuit-encapsulating portion, the receiver leads being flat plates, wherein when a direction in which the connecting terminal extends is a first direction, and a plane parallel to the first direction is a first plane, the first emitter lead and the second emitter lead protrude from the circuit-encapsulating portion in a direction parallel to the first plane and intersecting with the first direction, and extend in a direction opposite to the first direction, the first receiver lead and the second receiver lead protrude from the circuit-encapsulating portion in a direction parallel to the first plane and intersecting with the first direction and opposite to a direction in which the first emitter lead and the second emitter lead protrude, and extend in the direction opposite to the first direction, and the first emitter lead and the second emitter lead, and the first receiver lead and the second receiver lead are deformed to allow the light receiver and the light emitter to face each other, wherein the first emitter lead includes a first emitter lead portion that protrudes from the circuit-encapsulating portion in a direction parallel to the first plane and intersecting with the first direction, and extends in a direction opposite to the first direction; a second emitter lead portion that extends from the first emitter lead portion in one of an inward direction or an outward direction along an optical axis of the light; a third emitter lead portion connected to the second emitter lead portion; and a fourth emitter lead portion that extends from the third emitter lead portion in the other one of the inward direction or the outward direction along the optical axis, the fourth emitter lead portion includes a first bending portion that is bent along a first bending line, the first receiver lead includes a first receiver lead portion that protrudes from the circuit-encapsulating portion in a direction parallel to the first plane and intersecting with the first direction, and extends in a direction opposite to a direction in which the first emitter lead and the second emitter lead protrude, a second receiver lead portion that extends from the first receiver lead portion in one of an inward direction or an outward direction along the optical axis; a third receiver lead portion connected to the second receiver lead portion; and a fourth receiver lead portion that extends from the third receiver lead portion in the other one of the inward direction or the outward direction, and the fourth receiver lead portion includes a second bending portion bent along a second bending line.
