PROBLEM TO BE SOLVED: To provide the LC filter which is furthermore miniaturized. SOLUTION: Inductors L1-L3 and capacitors C1-C3 are arranged in parallel alternately, a plurality of inductors 12 (L-L3) connected in series to form a signal wire 14, conductors of the signal wire 14 interconnecting the inductors 12 (L1-L3), a conductor interconnecting a ground wire 15 to the capacitors C1-C3 are located close to each other so as to be 10μm-100μm thereby forming prescribed stray capacitance. Furthermore, the inductors 12 (L1-L3) and the capacitors C1-C3 are arranged closely so as to have prescribed stray capacitance between the signal wire 14 making up of the inductors 12 and the capacitor 13 and between electrodes above and under a dielectric layer of the capacitor 13 and the adjacent inductor 12 respectively.
