Abstract
According to an aspect, a detection device includes: a light-transmitting light guide plate that has a first surface on one side in a first direction and on which an object to be detected is to be placed so as to overlap the first surface; an optical sensor that is disposed on the other side in the first direction with respect to the light guide plate so as to overlap the light guide plate and includes photodiodes; a light source that is adjacent to the light guide plate in a second direction intersecting the first direction and is configured to emit light to a side surface of the light guide plate; and an antenna coil overlapping at least one of the light guide plate and the optical sensor as viewed in the first direction. The optical sensor, the light source, and the antenna coil are electrically coupled to a control board.
