<p>PROBLEM TO BE SOLVED: To provide a substrate for an inkjet head capable of easily providing an embedding groove on a substrate main body, into which a piezoelectric is embedded.SOLUTION: On a substrate main body 31, it is provided: a straight embedding groove 32 comprising second side surfaces 34a, 34b facing first side surfaces 30a, 30b of a piezoelectric 7. On both side of a base part 38 extending in a longitudinal direction of the embedding groove, a spacer 37 comprising a pair of guide parts 39a, 39b is provided. After adhesive agent 44 is supplied to bottom section of the embedding groove, the spacer is arranged on the substrate main body in a manner a guide part bridges the embedding groove. When the piezoelectric is pushed into the embedding groove together with the spacer, a gap corresponding to the thickness of the guide part is provided between the first side surfaces of the piezoelectric and the second side surfaces of the embedding groove and the adhesive agent supplied to the bottom section of the embedding groove is introduced into the gap. Thereafter, the adhesive agent is hardened so as to fix the piezoelectric in the embedding groove of the substrate main body.</p> |
