Abstract
A multi-laminated chip inductor (10) comprising a chip (11) provided therein with a coil (12) made by laminating insulating material sheets having internal conductors (21a) formed thereon and connecting the internal conductors (21a) into a helical shape and with lead internal conductors (22a through 25a) making connection between ends of the coil (12) and external terminal electrodes, and having external terminal electrodes (13a and 13b) formed on the surface of the chip (11) parallel to the winding center-line of the coil (12). Thereby, as the magnetic flux generated by the coil (12) does not intersect the plane of the external terminal electrodes (13a, 13b), eddy current within the external terminal electrodes (13a, 13b) can be prevented from generating and, the inductance values can be changed easily, by changing the connection position of the lead internal conductors (22a through 25a) with a coil end.
