To provide a chemical sensor that enables high detection accuracy. A chemical sensor includes a substrate, two or more magnetoresistance-effect elements disposed side by side in a substrate in-plane direction over the substrate, a first film disposed over a region between the magnetoresistance-effect elements adjacent to each other, and a second film disposed over the magnetoresistance-effect elements, wherein the second film has higher solubility in a specific liquid than the first film.
