Abstract
The invention relates to a chip inductor and its manufacturing method, in which an appropriate insulation is applied between adjacent linear conductors of the coil unit to prevent occurrence of short-circuit and to enhance electric characteristics, and moreover the mounting surface by the exterior unit is a flat surface, so that appropriate mounting is realized. The constitution includes a square columnar main body ( ) made of an insulating material, electrode units ( ) disposed at both ends of this main body ( ), a coil unit ( ) connected to the electrode units ( ) and disposed on the outer circumference of the main body ( ) between the electrode units ( ), and an exterior unit ( ) having this coil unit ( ) coated with an insulating resin ( ), in which the coil unit ( ) includes linear conductors ( ) and grooves ( ) formed by grooving a conductor layer ( ) covering the surface of the main body ( ), and the insulating resin ( ) is also formed in the entire inside of the grooves ( ).
