摘要： The present invention provides a catalyst for electrodes, said catalyst having excellent catalytic activity and being capable of contributing to the cost reduction of a PEFC. This catalyst for electrodes comprises: a porous support which has nanopores having a pore diameter of from 1 nm to 20 nm and micropores having a pore diameter of less than 1 nm; and a plurality of catalyst particles which are supported by the support. The catalyst particles are supported by both inner portions and outer portions of mesopores of the support, and contain Pt (zerovalent). If an analysis of the particle size distribution of the catalyst particles is performed using three-dimensional reconstructed images obtained through a STEM-based electron tomography measurement, the condition of formula (S1), namely (100 × (N10/N20) ≤ 8.0) is satisfied. In the formula, N10 represents the number of noble metal particles that are not in contact with pores having a pore diameter of 1 nm or more; and N20 represents the number of catalyst particles that are supported by the inner portions of the nanopores of the support.
