Abstract
A detection device includes: a housing having a first surface with a light-shielding property and a second surface with a light-transmitting property; a light source provided inside a first area of the housing and configured to emit light from the second surface contacting a measurement target such that the light travels toward the measurement target; a first optical sensor provided inside the first area and capable of receiving light from the second surface; and a second optical sensor provided inside a second area different from the first area of the housing. The housing has an opening formed in the first surface of the second area and that allows light from an outside of the housing to pass therethrough to an inside of the housing. The second optical sensor configured to receive light from the opening and has a side that faces the second surface and is shielded from light.
