NARROW-PITCH CONNECTOR, ELECTROSTATIC ACTUATOR, PIEZOELECTRIC ACTUATOR, INK-JET HEAD, INK-JET PRINTER, MICROMACHINE, LIQUID CRYSTAL PANEL, AND ELECTRONIC APPARATUS

摘要

A narrow pitch connector which is capable of coping with fine pitches between electrodes, an electrostatic actuator, a piezoelectric actuator, a micro machine and a liquid crystal panel each including the narrow pitch connector, an ink jet head using the electrostatic actuator or the piezoelectric actuator, and an ink jet printer and an electronic appliance which are incorporated with the ink jet head. A narrow pitch connector (20) comprising a substrate (22) on which a plurality of first terminal electrodes (30),a plurality of second terminal electrodes (32), and wires (24) electrically connecting the first terminal electrodes (30) with the second terminal electrodes (32) having a function of making conversion from a pitch of the first terminal electrodes (30) to a pitch of the second terminal electrodes (32) are formed, wherein grooves (32A) are formed between the first terminal electrodes (30) respectively.
