Abstract
Provided is an electrode catalyst that can exhibit sufficient performance, is suitable for mass production, and is suitable for reducing production costs, even when containing a relatively high concentration of chlorine. The electrode catalyst has a core-shell structure including a support; a core part that is formed on the support; and a shell part that is formed so as to cover at least one portion of the surface of the core part. The electrode catalyst concurrently fulfills conditions expressed by the following formulae (1) and (2): (X1/M)≦1.2 . . . (1) (X2/M)≦47.0 . . . (2) (in the formula (1) and the formula (2), M represents an amount of substance (number of atoms) of one or more constituent metal elements of the shell part, X1 represents an amount of substance (number of atoms) of bromine (Br), and X2 represents an amount of substance (number of atoms) of chlorine (Cl)).
