PROBLEM TO BE SOLVED: To improve connection strength between a connected object and a wiring board.SOLUTION: An input contact of a piezoelectric actuator and a board-side contact of a COF of a printer are electrically connected via a conductive part made of conductive resin containing metallic material and thermosetting resin. The piezoelectric actuator and the COF are mechanically connected to each other via a reinforcement part 62 in addition to the conductive part. The reinforcement part 62 is located at a position different from the conductive part in the COF 50 and arranged at a position across a surface of a solder resist 54 and a surface of a flexible substrate 52. |
