Claims

[Claims for Utility Model Registration] (1) A plurality of piezoelectric elements each having a substantially rectangular cross section arranged side by side, each piezoelectric element having a side surface facing each other and a side surface adjacent to the opposite side surface; A print head for a dot printer comprising lead wires for supplying voltage to the elements, characterized in that a connection portion between each piezoelectric element and the lead wire is provided on the adjacent side surface of the piezoelectric element. (2) Connection between each piezoelectric element and the lead wire in a print head of a dot printer that has a plurality of piezoelectric elements arranged in a circular or arc shape and each having a substantially rectangular cross section and a lead wire that supplies voltage to each piezoelectric element. A print head for a dot printer, characterized in that a portion is provided at an end of the circle or arc on the side far from the center on the side surface where adjacent piezoelectric elements face each other.
