摘要： 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.
