Provided is an LC filter that can obtain large insertion loss in a high-frequency band. The following are provided: a core 1 in which on both ends of a winding core part 1a a pair of collar parts 1b, 1c are formed; a winding 2; and a pair of signal-use external electrodes 5, 9. At least one of the pair of collar parts 1b, 1c comprises a laminated body in which an internal electrode and a dielectric layer 4 are alternatingly laminated, and the one collar part is provided with a grounding-use external electrode 6 (10). The internal electrode is provided with a first internal electrode 3a (7a) and a second internal electrode 3b (7b) which are alternatingly disposed. The first internal electrode 3a (7a) is connected to the signal-use external electrode 5 (9), and the second internal electrode 3b (7b) is connected to the grounding-use external electrode 6 (10). |
