A packing is formed by an elastomer, and a connector housing is formed by a resin having a mutual solubility with the elastomer. The packing is inserted into a cylindrical section of the connector housing, and a flange section of the packing is brought into contact with a bottom section of the cylindrical section. Next, by using an ultrasonic wave horn, a ring-shaped contact section between the flange section and the bottom section is excited by an ultrasonic wave, and the ring-shaped contact section is fused to form a ring-shaped sealing section. Thus, the packing is firmly fixed to the connector housing. |
