    • Disclosed are a sheet-type secondary battery in which sealing performance and insulating performance around an electrode terminal can be secured even if a flexible laminated sheath and the electrode terminal are bonded via a bonding resin, and also a manufacturing method therefor. The sheet-type secondary battery includes: a laminated sheath (2) including an inner layer (2a) made of a thermoplastic resin and a metal layer (2b) ; and electrode terminals (3), each of which is connected electrically to an internal electrode pair (1) and passes through a heat seal portion (20) of the laminated sheath (2) in a hermetic manner so as to be led out externally. The laminated sheath (2) and the electrode terminal (3) are bonded with a bonding resin (5) at the heat seal portion (20) in which the electrode terminal (3) is interposed. The inner layer (2a) of the laminated sheath (2) opposed to the electrode terminal (3) has an excess resin receiving portion (20a) formed thereon for receiving an excess resin in a heat sealing process. The excess resin receiving portion (20a) is not formed in a heat seal portion (20P) at which the inner layers (2a) of the laminated sheaths (2) are bonded.

    • 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.
