    摘要: A processing device is provided with a circuit connected to a first conductive portion and a second conductive portion. An AC voltage source produces an AC waveform voltage obtained by adding a bias voltage to an AC voltage for capacitance measurement. The AC waveform voltage is applied between the first conductive portion and the second conductive portion through the measurement probes. The moment the AC waveform voltage is applied to the circuit with a switch closed, an inrush current flows through the circuit based on a potential difference of the bias voltage. This inrush current causes dielectric breakdown in the conductive resin, thereby securing the continuity of the conductive resin. With the continuity of the conductive resin secured, a capacitance of the piezoelectric body is measured by the AC waveform voltage, and it is determined whether or not the piezoelectric body is normal.

    摘要: A piezoelectric element 13 has a common electrode 19 that receives electricity from a terminal 57. The terminal 57 has a through hole 67 and an electric insulating layer 61. The piezoelectric element 13 is arranged so that the common electrode 19 faces the electric insulating layer 61 of the terminal 57. A liquid stopper 69 is formed around the through hole 67 so as to come between the common electrode 19 and the terminal 57 when the common electrode 19 and terminal 57 are set to face each other. A liquid conductive adhesive 71 is injected into the through hole 67 to fill a gap defined by the liquid stopper 69 between the terminal 57 and the common electrode 19 and secure electric connection between the terminal 57 and the common electrode 19. This configuration improves the reliability of wiring to the piezoelectric element and prevents the piezoelectric element from being damaged.
