ELECTRIC HEATING TYPE CARRIER AND EXHAUST GAS EMISSION CONTROL DEVICE
To provide an electric heating type carrier and an exhaust gas emission control device capable of excellently suppressing temperature difference generated in a base layer during energization and excellently suppressing heat conductivity to a metal electrode, to suppress a crack in the base layer.SOLUTION: An electric heating type carrier comprises: a ceramic-based columnar honeycomb structure having an outer peripheral wall, and a partition wall disposed inside the outer peripheral wall and partitioning a plurality of cells forming a flow path from one end face to the other end face; an electrode layer disposed on the surface of the outer peripheral wall of the columnar honeycomb structure; and a metal electrode provided on the electrode layer via two or more conductive base layers separated from each other. The base layer has a recess forming a space between itself and the metal electrode.SELECTED DRAWING: Figure 3
【課題】通電時に下地層内に生じる温度差が良好に抑制されると共に、金属電極への熱伝導を良好に抑制することで、下地層のクラックを抑制可能な電気加熱式担体及び排気ガス浄化装置を提供する。【解決手段】外周壁と、外周壁の内側に配設され、一方の端面から他方の端面まで貫通して流路を形成する複数のセルを区画形成する隔壁と、を有するセラミックス製の柱状ハニカム構造体と、柱状ハニカム構造体の外周壁の表面に配設された電極層と、電極層上に、互いに離間した２つ以上の導電性を有する下地層を介して設けられた金属電極とを備え、下地層は、金属電極との間に空間を構成する凹部を有する電気加熱式担体。【選択図】図３
