When a light emitting element alternately switches between a lighting state in which the light emitting element emits light into a body and a non-lighting state in which the light emitting element does not emit light, the storage unit stores a value of a first digital signal representing an output state of a light receiving element that receives light transmitted through or reflected by the body at timing of the lighting state, and a value of a second digital signal representing an output state of the light receiving element at timing of the non-lighting state. The subtractor subtracts the second digital signal value stored in the storage unit from the first digital signal value stored in the storage unit.

The driver drives one or more light emitting elements to emit an optical signal having a light intensity that varies periodically.

The voltage signal generator outputs a voltage signal from which a frequency component which is equal to or lower than a predetermined frequency contained in the acquired electric signal has been removed. The amplifier amplifies the voltage signal and outputs an amplified signal.
