Patent ID: 8591614

Claim:
A method of manufacturing an exhaust gas purifying apparatus, comprising: providing an exhaust gas-treating body; providing a holding sealing material including inorganic fibers, the holding sealing material having a mat shape with a length, a width and a thickness, the holding sealing material having a first end face and a second end face each provided approximately in parallel with a width direction, the holding sealing material having the length shorter than a circumferential length of the exhaust gas-treating body; winding the holding sealing material around a periphery of the exhaust gas-treating body to form a gap between the first end face and the second end face of the holding sealing material; housing the exhaust gas-treating body with the holding sealing material in a casing so that the holding sealing material is disposed between the exhaust gas-treating body and the casing; disposing at least one of a first electrode member and a first sensor at the gap of the holding sealing material so that at least one of the first electrode member and the first sensor is connected to the exhaust gas-treating body, passes through the holding sealing material, and penetrates the casing; and disposing at least one of a second electrode member and a second sensor after winding the holding sealing material so that at least one of the second electrode member and the second sensor is connected to the exhaust gas-treating body, passes through the holding sealing material, and penetrates the casing, wherein the holding sealing material has a penetration portion penetrating the holding sealing material in a thickness direction, and at least one of the second electrode member and the second sensor is disposed at the penetration portion of the holding sealing material, and wherein a diameter of a cross section of the penetration portion of the holding sealing material is from about 1 mm to about 100 mm.
