Abstract: A pulse wave sensor includes: a white LED emitting white light to a human body; a G sensor converting, into a first electrical signal, green light included in light emitted from the white LED and reflected within the human body; an R sensor converting, into a second electrical signal, red light included in the light emitted from the white LED and reflected within the human body; and an arithmetic control unit configured to generate a signal showing a heart rate based on a level difference between the first electrical signal and the second electrical signal. Therefore, a distance between the G sensor and the R sensor does not have to be increased, so that an apparatus can be reduced in size.

Abstract: The living body information sensor according to the present invention can be attached to a living body. A light emitting unit emits light to the living body. The light receiving unit receives reflected light from the living body that is included in the light emitted by the light emitting unit to the living body, and outputs a signal according to intensity of the reflected light. A control device generates information about the living body based on the signal from the light receiving unit. The control device controls the light emitting unit to turn on and off in an alternate manner. The control device sets a total of a turn-on time of the light emitting unit in a prescribed time interval to be smaller when the living body information sensor is attached to the living body than when the living body information sensor is not attached to the living body.
