Abstract
According to one embodiment, an optical sensor includes an optical waveguide module and a specimen area. The specimen area is provided adjacent to the optical waveguide module, and is configured to hold a specimen. The specimen area includes a sensing area and a precipitation area. An optical change occurs in the sensing area. A precipitate of the specimen is precipitated in the precipitation area. The precipitation area is placed at a different position from a position of the sensing area which is attached to the optical waveguide module.
