A resonator is connected in parallel to at least one serial-arm-connected resonator in a resonator type filter having a serial arm and a parallel arm. At this time, the resonance frequency of the resonator connected in parallel is set to be substantially the same as the resonance frequency of the parallel-arm-connected resonator.This makes it possible to prevent the deterioration of attenuation levels at the lower-frequency side of the filter, caused by an increase in the resistance of a connection element due to an increase in packaging density.

A connecting structure of a lead wire is electrically connected to an electrode in which a polarized electrode layer is formed on a surface of a current collector plate. A region of the electrode, to which the lead wire is to be joined, is free from the polarized electrode layer. The lead wire is joined to the current collector plate by means of stitching and then compressed thereto. This connecting structure may keep a capacitance of a capacitor and improve contact reliability. An electric double layer capacitor having the structure and a method for manufacturing the capacitor are also provided.
