This finger-worn device comprises an annular structure configured to be worn on a finger. A first light source and a second light source held by the annular structure emit light of mutually different wavelengths to a space surrounded by the annular structure.

The control unit further performs biological information measurement processing for obtaining biological information on the basis of at least one of the first light reception level and the second light reception level.
