ABSTRACT:
Bondage of an ink supply needle and a holder base is appropriately performed by ultrasonic welding. A filter is housed in a filter storing part from the upper side of the holder base, and a needle-side fitting part is fitted into a base-side fitting part from the upper side of the holder base. Then, when the ink supply needle and the holder base are welded by ultrasonic waves, the energy of ultrasonic oscillation is concentrated on a contact portion of a protruded part of a needle-side bondage part and a base-side bondage part, and the contact portion of the protruded part is melted out so as to weld the ink supply needle and the holder base. Thereby, the contact portion of the ink supply needle and the holder base is appropriately bonded by ultrasonic welding as a whole without any gap.
