ABSTRACT:
To provide a high capacity thin-type secondary battery suitably formed into a module and having no thickness fluctuation, excellent quality stability, and excellent heat radiation properties, by using a sheet-like separator having expansion anisotropy due to penetration of an electrolytic solution. A method of producing a thin-type secondary battery includes the steps of: sandwiching a sheet-like separator having expansion anisotropy due to penetration of an electrolytic solution, by a sheet-like electrode pair; inserting the separator sandwiched by the electrode pair and injecting the electrolytic solution, into a thin-type outer wrapper having an opened portion; penetrating the electrolytic solution into the separator without fixing motion of the separator in a maximum expanding direction and in a state where the maximum expanding direction of the separator and a penetrating direction of the electrolytic solution are substantially parallel to each other; and sealing the opened portion into a tightly sealed state.
