Abstract: A catalyst comprising: a titanium oxide having an anatase-type crystal structure, and having the vertices and the ridge lines, wherein in a single titanium oxide particle, a vertex density per unit surface area is 8.0×10−4 nm−2 or more, and a ridge line density per unit surface area is 5.0×10−2 nm or more, or a ridge line density per unit volume is 8.0×10−3 nm−2 or more. A complex comprising: a material having a porous structure; and said catalyst. A membrane electrode assembly comprising: an anode; cathode; and an electrolyte membrane, wherein the cathode carries said catalyst on at least a surface of the cathode.
