Abstract
The vibration device includes a piezoelectric element having a connection terminal exposed from a main surface of the piezoelectric element, a first resin layer having conductivity and covering the connection terminal of the piezoelectric element to be electrically connected to the connection terminal, a wiring member overlapping the main surface of the piezoelectric element to cover the first resin layer, including a wire electrically connected to the first resin layer, and extending beyond one end of the piezoelectric element when viewed in a thickness direction of the piezoelectric element, and a second resin layer integrally covering the main surface of the piezoelectric element and the wiring member. The second resin layer includes a first layer in direct contact with the piezoelectric element and the wiring member, and a second layer covering the piezoelectric element and the wiring member via the first layer.
