PROBLEM TO BE SOLVED: To provide a high quality and low cost electric double-layer capacitor and a reasonable manufacturing method thereof with which excellent energy-volume efficiency can be ensured and connection with external wires can also be realized easily. SOLUTION: The electric double-layer capacitor comprises a laminate 30 which is constituted by the predetermined number of positive and negative electrodes 20 and separators 25 which are provided among these electrodes; a conductive portion 22 which is exposed like a belt from a polarizing electrode 27 as a part of a collecting electrode 23 of each electrode 20; and a sealing portion 40 for sealing, together with internal and external boundaries of a vessel 10, a conductive portion 22 which is led to the external side from the internal and external boundaries of the vessel 10 for accommodating the laminate 30 together with the electrolyte. The manufacturing method thereof comprises the step of manufacturing a sheet 15A, as a material to form the positive and negative electrodes 20, which is provided with a non-laminated layer region 15b for exposing a raw material layer of the collecting electrode 23, and a hot melt resin 26a of the predetermined width which is bonded to the constant location of the non-laminated layer region 15b from the laminated layer region 15a of the raw material layer of the collecting electrode 23 and the raw material layer of the polarizing electrode 27 and the raw material layer of the polarizing electrode 27.
