A rotating electric machine in which a coil wrapped in an insulating sheet is fixed to a slot provided in an iron core, wherein the insulating sheet has a porous structure, the coil and the insulating sheet, and the insulating sheet and the iron core are each fixed by an insulating varnish which is brought into a dispersion state by ultrasonic irradiation, and a mixed layer in which the insulating varnish and the insulating sheet are mixed due to penetration of the insulating varnish is formed in at least a predetermined range from a surface layer to an interior of the insulating sheet.

A method is provided for manufacturing a fuel-cell stack that has a laminate including of a plurality of fuel cells that are laminated together. In each of these fuel cells, an MEA has an anode and a cathode joined respectively to the two sides of an electrolyte membrane is sandwiched between a pair of separators. The aforementioned method has the following steps: a sealing member layout step, in which fuel cells with sealing members applied at least between adjacent fuel cells are laminated together, forming a fuel cell module; and a pressure application step, in which pressure is applied to the fuel cell module in the lamination direction of the fuel cells, forming sealed regions from the sealing members. The lamination-direction thickness of the fuel cell module is controlled by controlling the amount of pressure applied to the fuel cell module in the pressure application step.
