A panel device, which is capable of increasing vibration amplitude of a panel without increasing power consumption of a piezoelectric element, includes a panelrectangular in shape and piezoelectric elementsalso rectangular in shape disposed on the panelfor vibrating the panel, such that each of the piezoelectric elementsis disposed having one side at a slant relative to one side of the panel

Panel device

A thermal head capable of dissipating heat accumulated in a heat accumulating layer efficiently and achieving clear printing, and a thermal printer including the thermal head are provided. A thermal head includes a substrate, a heat accumulating layer disposed on part of the substrate, a heat generating portion disposed on the heat accumulating layer, an electrode electrically connected to the heat generating portion, a protective layer that covers the heat generating portion and part of the electrode, and an insulating layer having thermal conductivity, the insulating layer covering part of a region of the electrode which region is not covered with the protective layer. The insulating layer covers part of the protective layer and extends over the heat accumulating layer.

Thermal head and thermal printer including the same

A thermal head in which battery effect-induced corrosion can be retarded while maintaining excellent anti-static capability in an upper conductive protective film, is provided. The thermal head includes a substrate, a heater element arranged on the surface of the substrate, an electrode layer connected to the heater element, and an upper conductive protective film for covering part of the electrode layer. In the thermal head, between the electrode layer and the upper conductive protective film is interposed a lower conductive protective film which is higher in specific resistance than the upper conductive protective film.
