ABSTRACT:
In a sensor for detecting a substance in liquid, recesses are provided in the upper surface of a base substrate. The recesses respectively accommodate SAW elements. A resin layer having openings is arranged such that the sensing portions at the upper surfaces of the SAW elements are exposed in the openings. A reaction film made of a material capable of binding to a target substance is also arranged so as to cover the sensing portion of at least one of the SAW elements. A liquid containing a target substance is fed from the openings.
