摘要：
An object is to provide a catalyst particle that can exhibit high activity. The catalyst particle is an alloy particle formed of platinum atom and a non-platinum metal atom, wherein (i) the alloy particle has an L12 structure as an internal structure and has an extent of ordering of L12 structure in the range of 30 to 100%, (ii) the alloy particle has an LP ratio calculated by CO stripping method of 10% or more, and (iii) the alloy particle has a dN/dA ratio in the range of 0.4 to 1.0.
