ELECTRIC HEATING TYPE CARRIER AND EXHAUST GAS PURIFICATION DEVICE
To provide an electric heating type carrier and an exhaust gas purification device capable of satisfactorily suppressing an increase in resistance due to damage to an electrode layer and deterioration of the electrode layer during energization heating.SOLUTION: There is provided an electric heating type carrier including: a columnar honeycomb structure comprising an outer peripheral wall and a porous partition wall that is arranged inside the outer peripheral wall and partitioning the inside space to form a plurality of cells that penetrate from one end face to the other end face so as to form a flow path; a pair of electrode layers arranged on the outer peripheral wall of the columnar honeycomb structure in a manner to face each other with interposed the central axis of the columnar honeycomb structure; a honeycomb structure having a protective layer covering the electrode layers in a manner where at least one part of the electrode layers is exposed; and a pair of metal terminals provided on the pair of electrode layers. The electrode layers are made of metal-ceramics mixed material and the part exposed from the protective layer of the electrode layers is electrically connected to the metal terminals.SELECTED DRAWING: Figure 1
【課題】通電加熱時の電極層の破損及び電極層の劣化による抵抗の増大を良好に抑制することが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多孔質の隔壁と、を有する柱状ハニカム構造部、柱状ハニカム構造部の外周壁の表面に、柱状ハニカム構造部の中心軸を挟んで対向するように配設された一対の電極層、及び、電極層の少なくとも一部が露出するように電極層を覆う保護層を備えたハニカム構造体と、一対の電極層上に設けられた一対の金属端子とを備え、電極層が金属−セラミックス混合部材で構成されており、電極層の保護層から露出している部分が金属端子と電気的に接続されている電気加熱式担体。【選択図】図１
