PROBLEM TO BE SOLVED: To provide a capacitor having such an object that, even if a collector is disposed at a middle position of a housing container, it is possible to wire in a space of the housing container efficiently, a production step is simple, a low ESR is possible and a reliability is enhanced in a contact between a leading electrode and the collector. SOLUTION: A bottom face of a body of a housing container 1 and a negative pole collector 5 serving as an intermediate collector and arranged at a position apart from a lid 7 and the bottom face of the housing container 1 are disposed in a stepped portion formed on an inner side face of the housing container 1, so as to overlap with an end of a negative pole leading electrode layer 10 formed on the housing container 1, for solderless connection by a compression force caused by a lid protrusion 7. A positive pole external electrode 9a and a negative pole external electrode 10a are connection electrodes with an external circuit, and a charge and discharge are carried out through the electrodes.
