发明名称 LAMINATED LC FILTER
摘要 PROBLEM TO BE SOLVED: To provide a laminated LC filter that reduces the break of a magnetic field generated in an inductor electrode due to other internal electrodes for composing capacity, and can improve characteristics in the filter. SOLUTION: This laminated LC filter has a laminate. In the laminate, inductor electrodes 51 and 52 for composing a resonance circuit, capacitor electrodes 31 and 32, and ground internal electrodes 61, 62, 21, and 22 are laminated via a dielectric sheet. The inductor electrodes 51 and 52 are formed in a flex or curvature shape, at the same time, an end section 51a is provided near the center section of the dielectric sheet, middle sections 51b and 52b are provided near the end section of the dielectric sheet, and the other end sections 51c and 52c are provided near the center section of the dielectric sheet. The capacitor electrodes 31 and 32, and the ground internal electrodes 61, 62, 21, and 22 are formed in a strip shape near the center section of the dielectric sheet, and at the same time are overlapped in parallel.
