The diffusion-limiting membrane holding plate mounting member 32 is provided so as to be movable in the direction toward and away from the electrode 3, and the diffusion-limiting membrane holding plate mounting member 32 can be positioned in a moving position in the separating direction or in a moving position in the approaching direction. a positioning section 13 that covers the upper surface of the diffusion-limiting membrane holding plate mounting member 32, and an openable/closable external cover 2 that covers the upper surface of the diffusion-limiting membrane holding plate mounting member 32; 1. A diffusion-limiting membrane mounting mechanism in a biosensor, characterized in that a positioning/releasing means 16 is provided. 2. The diffusion-limiting membrane mounting mechanism in the biosensor according to claim 1, wherein the diffusion-limiting membrane holding plate mounting member 32 is rotatably provided about one end thereof as a fulcrum. 3. Claim 1 of the above-mentioned utility model registration, in which the diffusion-limiting membrane holding plate mounting member 32 can be accommodated in or taken out from the groove 34 only by sliding the diffusion-limiting membrane holding plate 4. or the diffusion-limiting membrane attachment mechanism in the biosensor according to item 2. 4. The positioning part 13 is a swing member 67 having a guide groove 66 that engages with an engagement shaft 62 provided on the diffusion-limiting membrane holding plate mounting member 32, and the guide groove 66 is aligned with the center of swing. A diffusion-limiting membrane mounting mechanism in a biosensor according to claim 1 or 2, which has a pair of engaging portions 66a and 66b located at the 1st and 2nd claims. 5. The positioning release means 16 forcibly moves the diffusion limiting membrane retaining plate mounting member at the end of the closing operation of the external cover 2 to disengage the engagement shaft 62 and the engagement portion 66a. A diffusion-limiting membrane attachment mechanism in a biosensor according to claim 4 of the utility model registration claim.
