Title: LAMINATED LC FILTER
Abstract:
Provided is a laminated LC filter in which the Q value of the inductor constituting the LC resonator is high, and insertion loss is improved. One via conductor 5f on a second side E12, and two via conductors 5m, 5n on a fourth side E14, are connected to a track-shaped conductor pattern 17a, 27a, 37a of a first inductor L1, and conversely, two via conductors 5g, 5f on the second side E12, and one via conductor 5o on the fourth side E14, are connected to a track-shaped conductor pattern 17b, 27b, 37b of a second inductor L2, and the same relationship is repeated for third through fifth inductors L3-L5.
