The invention relates a wiring structure of a vibrator and a piezoelectric pump. On the basis of the recognition that it is difficult to obtain sufficient reliability of connecting parts with a conductive adhesive material only while attention is paid to using the conductive adhesive material instead of soldering, a wiring structure is obtained in which a connecting terminal and a film-like electrode are adhered to each other by a conductive adhesive material, and a pressing member which applies a force in a direction in which the connecting terminal is pressed against the film-like electrode is caused to abut on the connecting terminal.
