A pressing roller (32) which is supported by the movable plate (28) and can contact the outer peripheral surface of the housing (5);
2) an urging means (30) for urging the movable plate (28) in a contact direction with the outer peripheral surface of the housing (5);
8), the outer peripheral edge of the honeycomb tubular body (4) on the side closest to the pressing roller (32) and the housing (5).
And a laser welding torch (34) for focusing an irradiation laser at a contact portion (P) with an inner peripheral surface of the honeycomb laser body.
