摘要： PROBLEM TO BE SOLVED: To provide an electrocatalyst for a fuel cell capable of constituting a fuel cell in which fuel cell performance is hardly deteriorated by suppressing flooding at an electrode, and provide its manufacturing method. SOLUTION: This electrocatalyst for a fuel cell is constituted so that it contains a carrier having conductivity and catalyst particles carried on the carrier, and water-repellent particles having water repellency and conductivity are adsorbed to the carrier. Furthermore, its manufacturing method is constituted by having a dispersion liquid adjustment process in which the water-repellent particles and the carrier on which the catalyst particles are carried are dispersed into a non-aqueous solvent into which the water-repellent particles are soluble, and a deposition process of the water-repellent particles in which water-repellent particles are deposited onto the carrier surface with which solubility of the water-repellent particles in the dispersion liquid is reduced.
