<P>PROBLEM TO BE SOLVED: To provide a high-performance low-pass filter which is made simple in processes and also wide in pass band, and large in an attenuation gradient. Ž<P>SOLUTION: A low-pass filter is constituted by using an anode body 1 constituted of a valve operating metal in which enlargement processing is not applied to a surface to connect in parallel a plurality of double-terminal type solid-state electrolytic capacitors 30a, 30b having different electric lengths calculated from a cutoff frequency and molding them with an exterior resin. Lengths La, Lb of cathodes 7 of the double-terminal type solid-state electrolytic capacitors 30a, 30b are set to 1/4 of electric lengths. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
