Title:
COIL AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2016021436
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve that a coil conductor has a smaller circumference length, a lower resistance, and higher inductance by using a high permeability magnetic material, such as an amorphous material, for a core.SOLUTION: A coil includes: first and second cores (4-1, 4-2) made of a high permeability magnetic material, which respectively have through holes (12) that permit passage of coil conductor pieces and are disposed by making the through holes parallel to each other; cases (core cases 6-1 and 6-2) which respectively accommodate therein the first core and the second core; and a coil conductor that circulates between the first and second cores by coupling an end portion of at least one of the coil conductor pieces (8-1, 8-2) respectively passing through the through holes (12) of the first and second cores to an outside of the cases.SELECTED DRAWING: Figure 1
