PROBLEM TO BE SOLVED: 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.SOLUTION: 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.COPYRIGHT: (C)2014,JPO&INPIT【課題】湿度が高く、酸性またはアルカリ性に曝される可能性ある水回り空間において使用可能な、耐久性ある脱臭触媒の提供。【解決手段】金属基材と、中間層と、脱臭触媒層とを少なくとも有してなり、空気が金属基材の連通口を通り、触媒層と接触して空気中に含まれる臭気物質が分解および/または吸着されて脱臭がされる脱臭触媒であって、中間層が、連通口の双方の開口のエッジ部において金属基材を保護するのに充分な厚さで形成されてなり、水周り空間において用いられることを特徴とする脱臭触媒である。【選択図】図4
