Abstract
An optical sensor () includes a sensor chip member () having an optical waveguide layer (), a combination of an incidence end grating () and an output end grating () spaced from each other, in contact with the optical waveguide layer (), and a reaction reagent () provided on the optical waveguide layer () to detect as an optical change a quantity of measurement object interposed between the incidence end grating () and the output end grating (), and a chamber member () to have, when the sensor chip member () is assembled, a facing surface (F) in position facing the optical waveguide layer (), and a gap (I) defined between the optical waveguide layer () and the facing surface (F), the reaction reagent () being disposed in the gap (I).
