Provided is a sheet-type secondary battery capable of preventing damage to sheet-type electrodes when the sheet-type electrodes are connected, and also allowing an arbitrary number of the sheet-type electrodes to be laminated so as to easily realize a high-capacity sheet-type secondary battery and a manufacturing method therefor. In the sheet-type secondary battery, connecting parts between a positive electrode lead (3 a) and multiple sheet-type positive electrodes (11) and between a negative electrode lead (3b) and multiple sheet-type negative electrodes (13) are formed by laminating the multiple sheet-type positive electrodes (11) and the multiple sheet-type negative electrodes (13) on the corresponding positive electrode lead (3a) and on the corresponding negative electrode lead (3b), respectively, to thereby establish the connections therebetween, and the connection parts each have a conductive connection protective layer formed in between the laminated multiple sheet-type positive and/or negative electrodes. |
