PROBLEM TO BE SOLVED: To provide an immunoassay carrier capable of improving the measurement sensitivity of an immunoassay because there is a problem that a conventional immunoassay carrier cannot perform a highly sensitive measurement. In a glass carrier to which an antibody is bound, an antibody and a carrier having a functional group (A) of 5 × 10 −7 mol / m 2 to 1 × 10 −5 mol / m 2 based on the surface area of the carrier, A carrier for immunoassay, which is bound with a bi-crosslinking reagent (B) having a spacer arm length (angstrom) of 5 to 25.
