Abstract
A non-aqueous secondary battery includes: a positive-electrode collector layer; a positive-electrode layer formed on one surface of the positive-electrode collector layer; a negative-electrode collector layer; a negative-electrode layer formed on one surface of the negative-electrode collector layer so as to be opposed to the positive-electrode layer; a separator provided between the positive-electrode layer and the negative-electrode layer; and a positive-electrode-side insulating layer and a negative-electrode-side insulating layer respectively formed on another surface of the positive-electrode collector layer and another surface of the negative-electrode collector layer. Circumferential inner surfaces of peripheral edges of the positive-electrode collector layer and the negative-electrode collector layer are joined with a sealing agent including at least a positive-electrode fusion layer, a gas barrier layer, and a negative-electrode fusion layer. The positive-electrode-side insulating layer and/or the negative-electrode-side insulating layer has a battery-side recess provided on a surface.
