Abstract
In order to provide a single-unit sensor which serves as both an illuminance sensor and a proximity sensor, the sensor () includes a light receiving element section (E), an infrared cut-off filter (IRcutF), and a switching section (SWS) for switching spectral characteristics of the light receiving element section (E). The infrared cut-off filter (IRcutF) has an opening, and an infrared light receiving P-N junction (PDir) is provided at a location deeper in a substrate than a visible light receiving P-N junction (PDvis).
