Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress generation of a crack to a catalyst support due to heat cycles.SOLUTION: An energization heating type catalyst device includes: a catalyst support 10 for supporting a catalyst; a pair of electrical diffusion layers 11 formed so as to face each other at an outer peripheral surface of the catalyst support 10; and a wiring member 30 fixed to each electrical diffusion layer 11, where the catalyst support 10 is heated by energization via the wiring member 30. Each electrical diffusion layer 11 is formed by being divided into multiple regions (11a, 11b) in an axial direction of the catalyst support 10.SELECTED DRAWING: Figure 3 【課題】熱サイクルによる担体へのクラック発生を抑制すること。【解決手段】触媒を担持する担体１０と、担体１０の外周面において対向して形成された一対の電気拡散層１１と、それぞれの電気拡散層１１に固定された配線部材３０と、を備え、配線部材３０を介して担体１０が通電加熱される、通電加熱式触媒装置である。それぞれの電気拡散層１１が、担体１０の軸方向において複数個の領域（１１ａ、１１ｂ）に分割して形成されている。【選択図】図３
