A catalytic converter includes a housing and a catalyst support disposed in the housing. The catalyst support includes a central electrode, a generally cylindrical honeycomb structure and a hollow cylindrical electrode disposing therein the honeycomb structure. The honeycomb structure includes first, second and third metal sheets which are spirally wound about the central electrode and corrugated in shape. The first metal sheet has an inner end electrically connected to the central electrode and an outer end electrically connected to the hollow cylindrical electrode. The radial distance between the central electrode and the second metal sheet is different from that between the central electrode and the third metal sheet. The third metal sheet is spaced away from an imaginary solid having a surface defined by imaginary straight lines extending from an axis of the central electrode in a radial direction and passing through a periphery of the second metal sheet.
