A method for manufacturing a laminated electrical storage device, the method including heating an external terminal by a heater that is not in contact with the external terminal and is provided near a portion of the external terminal that extends from a laminate case, and pressing opposed laminate films of the laminate case with a heated thermocompression bonding jig so as to thermocompression-bond each of the opposed laminate films to the external terminal and seal the laminate case.

Method for manufacturing laminated electrical storage device

A piezoelectric fan includes a vibration plate one end of which in a length direction is supported in a fixed manner and the other end of which in the length direction is a free end; and piezoelectric elements, attached on at least one of front and back surfaces of the vibration plate. In an intermediate portion of the vibration plate in the length direction, a right-angle bent portion is provided, and a plurality of divided blades are defined by slits in an area of the vibration plate extending from the free end to a position located a predetermined distance from the bent portion toward the free end. The piezoelectric element is attached on the portion of the vibration plate between the fixed end and the bent portion. Hence, variations in resonant frequency among the blades are reduced and the blades are efficiently excited using a common piezoelectric element.
