PHOTOELECTRIC SENSOR, PHOTOELECTRIC SENSOR MODULE, AND BIOLOGICAL INFORMATION MEASUREMENT APPARATUS

摘要

A photoelectric sensor includes a silicon substrate, a light emitter that emits first light, a light receiver that receives second light, a light emitter terminal that supplies the light emitter with electric power, and a light receiver terminal to which the light receiver outputs a signal, and the light emitter, the light receiver, the light emitter terminal, and the light receiver terminal are provided on the silicon substrate.
