Provided is a metal-resin complex that has a structure in which a plurality of metal particles are fixed to resin particles and, in the range of pH 3 to pH 10, the maximum value of the zeta potential is at least 5 mV and the minimum value is [zeta] 5 mV or less. In this metal-resin complex, it is preferable that, in the range of pH 3 to pH 10, the difference between the maximum value and the minimum value of the zeta potential is at least 20 mV; and it is further preferable that the zero point of charge of the zeta potential is in the range of pH 3.5 to pH 9.0. This metal-resin complex can be used in immunoassays and in immunoassay reagents as a labeled substance by making antigens or antibodies adhere to the surface of the metal-resin complex.
