Abstract
A manufacturing method of the present invention includes ejecting a melt 61 of a solid electrolyte onto at least one electrode plate selected from a positive electrode plate 20 and a negative electrode plate 30, thereby depositing the melt 61 onto the at least one electrode plate, and compressing the positive electrode plate 20 and the negative electrode plate 30 while sandwiching the melt 61, thereby forming a layered body including the positive electrode plate 20, an electrolyte layer 62 including the solid electrolyte, and the negative electrode plate 30. In accordance with this manufacturing method, a thin lithium secondary battery having excellent characteristics can be manufactured in a highly productive manner.
