PROBLEM TO BE SOLVED: To provide a capacitor capable of minimizing a fatigue of a collector projecting outside an electrode in electrically connecting each collector, and a manufacturing method thereof.SOLUTION: In a capacitor 100, a positive electrode material 120 or a negative electrode material 130 is provided on one face or both faces of a collector 110, and plural capacitor unit bodies 1U, 2U, 3U, 4U having separation films 140 are laminated on an outer face of the electrode material. The collector 110 includes a collector lead part 110' projecting outside the electrode material, the first capacitor unit body 1U including the positive electrode material 120, and the second capacitor unit body 2U including the negative electrode material 130. Three or more layers of the first capacitor unit bodies 1U and the second capacitor unit bodies 2U are alternately laminated to form a laminate. The collector lead parts 110' of the first capacitor unit bodies 1U are connected to each other, and the collector lead parts 110' of the second capacitor unit bodies 2U are connected to each other. The laminate is formed such that sides on which the collector lead parts 110' project form a staircases shape. |
