WIPO Patent Application WO/2013/027788
Kind Code:

Abstract:
A first coil section (11c) and second coil section (12c) having winding center portions as conductor openings (CW1, CW2), and shaped as two spirals are provided on a flexible substrate (10), along with a wiring section (112i) that electrically connects the first coil section and second coil section. A first slit (21) and second slit (22) are formed in the conductor openings (CW1, CW2) of the flexible substrate (10). Magnetic cores (31, 32) are inserted in the slits (21, 22) in the flexible substrate (10), and a T-shaped cut (S) is formed so as to demarcate a first area (A1), second area (A2) and third area (A3). The flexible substrate (10) is bent between, for example, the third area (A3; the area in which the wiring section is formed) and the first area (A1; the area in which the first coil section is formed), and between the third area (A3) and the second area (A2; the area in which the second coil section is formed).
