Zusammenfassung:	To suppress increase in electrical resistance of a metal terminal.SOLUTION: An electric heating type catalyst system includes a catalyst carrier 11 formed of a conductive material, a pair of metal terminals 20 attached to an outer surface of the catalyst carrier 11, a step-up/down converter 52 applying voltage between the pair of metal terminals 20, an inverter 60 provided between the pair of metal terminals 20 and the step-up/down converter 52 and switching an energization direction with respect to the pair of metal terminals 20, and a control device 90 for controlling the inverter 60. The control device 90 switches the energization direction with respect to the pair of metal terminals 20 when energization time with respect to the pair of metal terminals 20 reaches specified time.SELECTED DRAWING: Figure 3 【課題】金属端子の電気抵抗が増加することを抑制する。【解決手段】導電性の材質で形成された触媒担体１１と、触媒担体１１の外面に取り付けられている一対の金属端子２０と、一対の金属端子２０間に電圧を印加する昇降圧コンバータ５２と、一対の金属端子２０と昇降圧コンバータ５２との間に設けられ、一対の金属端子２０に対する通電方向を切り替えるインバータ６０と、インバータ６０を制御する制御装置９０と、を有し、制御装置９０は、一対の金属端子２０に対する通電時間が規定時間に達すると、一対の金属端子２０に対する通電方向を切り替える。【選択図】図３
