Abstract
The present invention relates to an inkjet recording head, which includes an ink cavity and an ink discharge port, a mounting member covering the ink cavity, an oscillating member, and a substrate to support the oscillating member. Various parts of the inkjet recording head are held together with adhesive. In attaching the piezoelectric element to the mounting member, opposing surfaces of the oscillating member and the mounting member are fixed to one another with adhesive. Then, the two members are pressed together, thereby causing excessive adhesive to emerge from between opposing surfaces of the oscillating member and the mounting member. The emerged adhesive is formed into chamfer to provide the oscillating member and the mounting member with areas of attachment that extend beyond the area of attachment that exists between the opposing surfaces.
