PROBLEM TO BE SOLVED: To provide an electrode body capable of suppressing short-circuit between a positive electrode and a negative electrode even when using resin particles for an insulation layer.SOLUTION: An electrode body 1 includes: a positive electrode 10; and a negative electrode 20. The positive electrode 10 includes: a positive electrode collector 11; and a positive electrode mixture layer 12 arranged on the positive electrode collector 11. The negative electrode 20 includes: a negative electrode collector 21; a negative electrode mixture layer 22 arranged on the negative electrode collector 21; and an insulation layer 23 which is arranged on the negative electrode mixture layer 22 and contains thermoplastic resin particles. Then, the resin particles in a position opposite to a cutting part at the end in the longitudinal direction of the positive electrode 10 are thermally deposited.SELECTED DRAWING: Figure 3 |
