More Information
Summary:An exhaust-gas-purification catalytic heating device houses a current heater (40) in a conductive metallic housing (37) where a catalytic unit (38) is housed. The current heater is arranged at an upstream side of the catalytic unit along a distribution direction of exhaust gas, the current heater has a negative electrode (43) directly coupled to the housing electrically coupled to an external ground wire (44). The current heater has a positive electrode (46) with which a rod-shaped terminal (47) is continuous, the terminal passing through the housing in an electrically insulating state so as to be electrically coupled to a power line (48) outside the housing, and the terminal has a portion protruding from the housing, the protruding portion being covered with a terminal cover (49).
