オトセンサ。[Claims for Utility Model Registration] In a photo sensor that includes a pair of light emitting element and light receiving element mounted on the upper surface of a substrate so as to be placed at a predetermined position in a light receiving and emitting part of a case, the amount of light emitted by the light emitting element is adjusted. A pair of protrusions are provided on the inner surface of the case to sandwich the current-limiting resistor, and the current-limiting resistor is sandwiched between the protrusions, and the lead wire of the current-limiting resistor is attached to the bottom surface of the substrate. A photo sensor characterized in that the lead wire is soldered to the conductive pad while the lead wire is in contact with the conductive pad.
