An electrolytic capacitor that includes: a resin molded body that includes a stack including a capacitor element and a sealing resin sealing a periphery of the stack; and an anode external electrode and a cathode external electrode on an outer surface of the resin molded body. The capacitor element includes: a valve-action metal substrate having a core and a porous portion along a surface of the core. The anode external electrode includes a first electrode layer in direct contact with the core of the valve-action metal substrate. The first electrode layer includes flat particles having an aspect ratio of 2 or more, and in a cross section, a long axis direction of the flat particles is arranged in a direction along the outer surface of the resin molded body.

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 method of manufacturing a piezoelectric ceramic device having excellent piezoelectric characteristics and high reliability is described. The method includes the steps of coating conductive paste containing Ag as a main component on each of a plurality of ceramic green sheets each containing a piezoelectric ceramic material, laminating the plurality of ceramic green sheets to form a laminate, and burning the laminate under an atmospheric condition in which the oxygen concentrations in a heating process and a retention process are about 21% by volume or more, and the oxygen concentration in a cooling process is about 0.05% by volume to 3% by volume.
