Abstract:
A secondary battery that can avoid reduction in battery capacity over the lapse of charge-discharge cycles and can exhibit high performance is provided. The secondary battery includes a laminated body having a pair of electrodes and an electrolyte layer provided between the pair of electrodes, the electrolyte layer including electrolyte particles, the laminated body having an end portion, and a restrictor provided so as to cover at least the end portion of the laminated body for restricting expansion of the electrolyte layer in the plane direction thereof.
