PROBLEM TO BE SOLVED: To provide a laminated-type noise filter, which is compact and is superior in filtering characteristic at a high-frequency band. SOLUTION: This noise filter is constituted by ground electrode layers 7a, 7b and 7c, each constituted of a ground internal electrode 11 which has first extensions 12 and 13 on the inside of a ceramics layers 10 or 21 to arranged directions of outside grounding electrodes, respectively, and which is connected to the external grounding electrodes, a capacitor electrode layer 8 constituted of a pair of capacitor internal electrodes 14 and 15, having extensions 16 and 17 from oppositely facing edge parts in the directions of external electrodes respectively, to the central part on a ceramics layer 10, and an inductor electrode layer 9 constituted by an inductor internal electrode 22, which is connected to outside electrodes arranged opposite on a ceramics layer 10.
