PROBLEM TO BE SOLVED: To provide an adsorption unit regenerating a filter by heating with high efficiency.SOLUTION: An adsorption unit includes: a deodorization filter part 23a formed to be discoid; radiator plates 23ca, 23cb disposed so as to cover a part of the surface of the deodorization filter part 23a; a PTC heater 23b heating a part of the deodorization filter part 23a by heating the radiator plates 23ca, 23cb; and a drive part moving the deodorization filter part 23a to the radiator plates 23ca, 23cb. The PTC heater 23b is disposed so that the orthogonally projected graphic of the PTC heater 23b to a virtual plane parallel to the deodorization filter part 23a does not overlap the orthogonally projected graphic of the deodorization filter part 23a to the virtual plane. The radiator plates 23ca, 23cb are formed so that the width dimension of the deodorization filter part 23a in a circumferential direction becomes larger toward an outer peripheral side from the center of the deodorization filter part 23a.SELECTED DRAWING: Figure 10 【課題】フィルタを高効率に加熱して再生すること。【解決手段】吸着ユニットは、円板状に形成される脱臭フィルタ部２３ａと、脱臭フィルタ部２３ａの一部の表面を覆うように配置される放熱板２３ｃａ、２３ｃｂと、放熱板２３ｃａ、２３ｃｂを加熱することにより脱臭フィルタ部２３ａの一部を加熱するＰＴＣヒータ２３ｂと、放熱板２３ｃａ、２３ｃｂに対して脱臭フィルタ部２３ａを移動させる駆動部とを備えている。このとき、ＰＴＣヒータ２３ｂは、脱臭フィルタ部２３ａと平行な仮想平面に対してＰＴＣヒータ２３ｂを正射影した図形が、脱臭フィルタ部２３ａを仮想平面に正射影した図形に重ならないように配置され、放熱板２３ｃａ、２３ｃｂは、脱臭フィルタ部２３ａの中心から外周側に向かうにつれて、脱臭フィルタ部２３ａの円周方向における幅寸法が大きくなるように形成されている。【選択図】図１０
