摘要： The present invention provides a coil and a method for manufacturing the same using a high magnetic permeability material such as an amorphous material for a core so as to achieve a shortened circling length of a coil conductor and a lower resistance as well as a higher inductance. The coil comprises first and second cores (4-1, 4-2) including through-holes in parallel for allowing penetration of coil conductor pieces (8-1, 8-2) made of a high magnetic permeability material, cases (core cases 6-1, 6-2) in which the first core and the second core are stored, and a coil conductor made up of the plurality of coil conductor pieces and circling between the first and second cores such that at least one end part of one of the coil conductor pieces (8-1) penetrating the through-holes (12) of the first core and the second core is coupled to an end part of the other coil conductor piece (8-2) on the outside of the cases.
