ABSTRACT:
A present invention is a chip-type inductor comprising a laminated structure (28) of a plurality of magnetic layers (1 to 8) in which linear conductive patterns (9 to 21) extending between the respective magnetic layers are connected successively in a form similar to a coil so as to produce an inductance component. The conductive patterns (12, 14, 16, 18, 20, 11 and 10) formed on the upper surfaces of the magnetic layers and the conductive patterns (9, 13, 15, 17, 19 and 21) formed on the lower surfaces of the magnetic layers are connected with each other in the interfaces of the magnetic layers and are also connected each other via through-holes (22 to 27) formed in the magnetic layers, so that the conductive patterns are continuously connected in a form similar to a coil.
