Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a positive electrode catalyst layer, with a large reaction area, excellent in diffusibility of a reaction gas and water, that is not corroded during charging reaction of an air secondary battery or oxygen generation reaction of an alkali type water electrolysis apparatus.SOLUTION: The catalyst layer includes a pore part formed by removing a pore part precursor from a catalyst layer skeleton organizer formed by molding a mixed material containing a metal carrying a catalyst, a pore part precursor, and a binder. 【課題】空気二次電池の充電反応やアルカリ形水電解装置の酸素生成反応時に腐食せず、また、反応ガスや水の拡散性に優れ、反応面積の大きい正極触媒層を提供する。【解決手段】触媒を担持した金属、空孔部前躯体、および、バインダーを含む混合材料を成型してなる触媒層骨格形成体から、空孔部前駆体を除去することにより形成された空孔部を有する触媒層とする。【選択図】図１
