Provided is a catalyst for solid polymer fuel cell that exhibits excellent initial activity and favorable durability and a method for manufacturing the same. The invention is a catalyst for solid polymer fuel cell which is formed by supporting catalyst particles including platinum, cobalt and manganese on a carbon powder carrier, wherein a composition ratio (molar ratio) among platinum, cobalt and manganese in the catalyst particles is Pt:Co:Mn=1:0.06 to 0.39:0.04 to 0.33, a peak intensity ratio of a Co—Mn alloy appearing in the vicinity of 2θ=27° is 0.15 or less with respect to a main peak appearing in the vicinity of 2θ=40° in X-ray diffraction analysis of the catalyst particles, and a fluorine compound having a C—F bond is supported at least on the surface of the catalyst particles. The amount of the fluorine compound supported is preferably from 3 to 20% with respect to the entire mass of the catalyst.
