description A support for a polymer electrolyte fuel cell catalyst satisfying the following requirements (A), (B), (C), and (D), and a producing method thereof, as well as a catalyst layer for a polymer electrolyte fuel cell and a fuel cell:(A) a specific surface area according to a BET analysis of a nitrogen adsorption isotherm is from 450 to 1500m2/g.(B) a nitrogen adsorption and desorption isotherm forms a hysteresis loop in a range of relative pressure P/P0of more than 0.47 but not more than 0.90, and a hysteresis loop area ΔS0.47-0.9is from 1 to 35 mL/g;(C) a relative pressure Pclose/P0at which the hysteresis loop closes is more than 0.47 but not more than 0.70; and(D) a half-width of a G band detected by Raman spectrometry in a range of from 1500 to 1700 cm-1is from 45 to 75 cm-1.
