Abstract To provide a catalyst for a fuel battery, of which the performance is enhanced further than conventional one.SOLUTION: A catalyst for a fuel battery according to an embodiment hereof comprises: a catalyst metal; and a carrier that supports the catalyst metal. Of the carrier, the ratio of inside and outside superficial areas (an outside superficial area of the carrier/an inside superficial area of the carrier) is 0.56-0.69. A percentage of the catalyst metal supported on the outer surface of the carrier is 23-35%.SELECTED DRAWING: Figure 1 【課題】本開示の目的は、従来よりも性能が向上した燃料電池用触媒を提供することである。【解決手段】本実施形態は、触媒金属と、前記触媒金属を担持する担体とを含む燃料電池用触媒であり、前記担体の内外表面積比（担体の外表面積／担体の内表面積）が０．５６～０．６９であり、担体の外表面に担持されている前記触媒金属の割合が、２３～３５％である、燃料電池用触媒である。【選択図】図１
