ABSTRACT:
A chamber support plate of an inkjet head is formed as a member different from a housing. The chamber support plate is formed with a plurality of grooves at high density by a dicing saw or the like. Piezoelectric elements are inserted into the grooves and adhered to a chamber plate. The plurality of grooves define comb teeth portions, which support the chamber plate at positions between adjacent piezoelectric elements.
