Abstract
A sensitive membrane includes: a membrane body containing a sensitive material; and a plurality of conductive particles included in the membrane body. The membrane body is expandable when adsorbing an analyte. An M1/M2 ratio of a mass M1 of the sensitive material to a mass M2 of the plurality of conductive particles is equal to or less than 0.4.
