Abstract
There is provided an optical sensor in which a reduction in size of a light-receiving part is achieved. This optical sensor is installed in a device, and includes a light-receiving elementfor receiving light coming from outside toward the device. The optical sensor detects the state of the received light. A linear optical waveguideis connected to the light-receiving elementso as to be capable of light propagation. The optical waveguidehas a front end portion serving as a light entrance portion on which light coming from the outside of the device is incident.
