Abstract
A diffusion-limiting membrane holding means for a sensor comprising: a slender resilient thin plate, of which one shorter side serves as an engagement side, and of which one longer side is provided at its predetermined position with an engagement portion, an opening being formed in the thin plate between the engagement side and the engagement portion; and a diffusion-limiting membrane integrally attached to the thin plate as covering the opening; whereby the resliency of the thin plate causes the diffusion-limiting membrane to be stuck to the surface of an enzyme electrode unit of a sensor, thus enhancing the accuracy of concentration measurement of a target substance to be measured.
