PROBLEM TO BE SOLVED: To provide a deodorization device that suppresses a temperature unevenness of an oxidation catalyst carried on a metal fin and decomposing odor at a low cost with a simple structure and is capable of retaining deodorization performance.SOLUTION: A deodorization device comprises: a heater 1 which extends in a first direction and in which a heat generation element 11 and a spacer element 12 are arranged in the first direction and a thermal propagation fin which is fixed to and in contact with the heater 1 with an adsorbent for adsorbing odor and an oxidation catalyst for decomposing odor carried on a surface of the thermal propagation fin. The edge of the heater 1 along the first direction is provided with a region in which the heat generation elements 11 are more densely arranged than in a central part of the heater 1.COPYRIGHT: (C)2015,JPO&INPIT【課題】金属フィンに担持されて臭気を分解する酸化触媒の温度ムラを低コストかつ簡易な構造で抑えて、脱臭性能の維持を図ることのできる脱臭装置を得ること。【解決手段】本発明は、第1の方向に延びるとともに前記第1の方向に沿って発熱素子11とスペーサ素子12とが配列されたヒータ1と、臭気を吸着する吸着剤と臭気を分解する酸化触媒とが表面に担持されて前記ヒータ1に接触固定された熱伝播フィンと、を備え、前記第1の方向に沿った前記ヒータ1の端部に、前記ヒータ1の中央部分よりも前記発熱素子11が密に配列される領域を設ける。【選択図】図5
