Abstract

A chemical sensor that enables high detection accuracy. A chemical sensor includes a substrate, a magnetoresistance-effect element disposed over the substrate, a first film disposed over the magnetoresistance-effect element, and a second film disposed in a region in the vicinity of the magnetoresistance-effect element or over a region in the vicinity of the magnetoresistance-effect element, wherein the second film has higher solubility in a specific liquid than the first film.
