Zusammenfassung:	To provide a catalyst for a fuel cell, including a catalyst particle that includes Pt as a main component, has a hollow nanoparticle structure, and has a larger ECSA than the conventional one, and a method of producing the catalyst for a fuel cell.SOLUTION: The catalyst for a fuel cell comprise: a carrier made of an electrically conductive material and catalyst particles supported on the surface of the carrier. The catalyst particle has a composition represented by PtxMz (where M is a metal element less noble than Pt, 0≤z
