Abstract: A piezoelectric drive device includes two vibrators having vibrating portions with piezoelectric elements and transmitting portions placed in the vibrating portions and transmitting drive forces to a driven member (e.g. a slider), and a fixing portion having through holes (first through hole, second through hole) into which pins or screws are inserted. The two vibrators are placed adjoiningly along a drive direction of the slider, and the fixing portion is placed between the two vibrators and fixing the two vibrators.

Abstract: An electronic apparatus includes an electronic component including a laminated body in which an intermediate layer is disposed between first and second substrates, the laminated body including a first side surface, a second side surface connected to one side of the first side surface, and a third side surface connected to the other side of the first side surface, a first terminal disposed on the first side surface of the first substrate, a second terminal disposed on the first side surface of the second substrate, and a recessed section that is positioned between the first and second terminals and that is recessed from the first side surface, a wiring substrate disposed to face the first side surface and a thermosetting adhesive that is located between the wiring substrate and the electronic component and that mechanically and electrically connects the wiring substrate and the electronic component to each other.

Abstract: A piezoelectric drive device includes: a vibrating body having a first surface and a second surface provided with a recessed portion; and a piezoelectric element provided on the first surface. The recessed portion and the piezoelectric element have an overlap region when viewed in a normal direction of the second surface.

Abstract: A piezoelectric actuator includes a vibrating plate having a piezoelectric material, and a contact part provided in an end portion of the vibrating plate in contact with a driven part, wherein the contact part has a first portion in contact with the driven part and a second portion provided between the first portion and the vibrating plate and having lower rigidity than the first portion. Further, a width of the second portion in a direction crossing an arrangement direction of the first portion and the second portion is smaller than a width of the first portion in the crossing direction.
