<P>PROBLEM TO BE SOLVED: To provide a laminated electronic component which keeps low impedance in a low frequency band and which makes high impedance in a high frequency band. <P>SOLUTION: Ferrite bead inductors 12, 13 comprise: a ferrite bead element 18 in which a magnet layer 24 and internal electrodes 25a to 25h are laminated in a long side direction of a main surface 18a so as to be made almost vertical to a mounting substrate; and first and second outer electrodes 19b, 20b arranged on a main surface 18b of the ferrite bead element 18 so as to be spaced from each other. The internal electrodes 25a to 25h have: a main electrode part 31 extending in a short side direction of the main surface 18a; and extraction electrode parts 33, 35 connecting the main electrode part 31 to the first and second outer electrodes 19b, 20b respectively. A width t1 of the main electrode part 31 in an opposing direction of the main surfaces 18a, 18b is a length equal to or longer than 50% of a thickness T of the ferrite bead element 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
