Abstract:
This detection device (1) comprises: a housing (200) which has a light-blocking first surface and a translucent second surface facing the first surface; a light source (60) which is provided within a first region (200A) of the housing (200) and which emits light such that the light is outputted from the second surface in contact with a measurement subject and travels toward the measurement subject; first light sensors (10A) that are provided within the first region (200A) of the housing (200) and are capable of receiving the light from the second surface; and second light sensors (10B) that are provided within a second region (200B), different from the first region (200A), of the housing (200). The housing (200) has openings (230) which are formed in the first surface in the second region (200B) and which allow light from the outside of the housing (200) to pass therethrough to the interior of the housing (200). The second light sensors (10B) receive light from the openings (230) and block light on the side facing the second surface.
