To provide a deodorization catalyst having durability, which can be used in a water section space that has high humidity and has such a possibility as to be exposed to acidic or alkaline atmosphere.
The deodorization catalyst has at least a metal substrate, an intermediate layer and a deodorization catalyst layer, and deodorizes air by passing the air through a communication port of the metal substrate, bringing the air into contact with the catalyst layer, and decomposing and/or adsorbing an odor material contained in the air. The intermediate layer is formed so as to have such a sufficient thickness as to protect the metal substrate at edge parts of both openings of the communication port. The deodorization catalyst is used in a water section space.
