Abstract

PURPOSE:To provide a water-repellent surface to the ink injection holes and improve maintenance and reliability by covering the surface of the head body provided with the ink supply outlets by the fluororesin sheet having the ink injection holes. CONSTITUTION:The outlets 3 of the ink supply passages 2 formed in head body 1 are provided on a plane 4 of the head body 1. On the plane 4 is adhered the fluororesin sheet 5 having the ink injection holes 6 of smaller diameter than the ink supply outlets 3 on their opposite positions. As a result, generation of defective typing due to ink wetting around the ink injection hole is decreased, and reliability and maintenance are improved.
