PROBLEM TO BE SOLVED: To provide resin particulates for a fuel cell which enable the fuel cell to exert a stable function when they are used between separators constituting the fuel cell and can prevent short circuiting between the separators and contacting of the separators with an electrolyte film. SOLUTION: The resin particulates for the fuel cell interposed between the separators of the fuel cell have a particle size of 10 to 100 μm, and a ≤30% CV value. The particulates, with the particle size within a certain range and the CV value small enough, will not bring forth fluctuations in intervals of the separators when used for the fuel cell, so that the fuel cell can exert a constant function. Further, problems of short circuiting between the separators, contacting of the separators with the electrolyte film or the like will not occur at the time of use of the fuel cell, hence a highly reliable fuel cell.
