Abstract
A thin-film type common-mode choke coil includes a laminated structure having a magnetic substrate; and electrically insulating layers and conductor layers laminated on the magnetic substrate in a direction of thickness, wherein said conductor layers form at least two coil conductors; at least two of the conductor layers are provided as spiral conductor patterns; and the spiral conductor patterns satisfy the expression: 5 μm≦W≦36 μm in which Wis the conductor width of each of the spiral conductor patters. The spiral conductor patterns may also satisfy the expression: 100 μm≦T*Win which T is the conductor thickness of each of said spiral conductor patterns or satisfy the expression: W<T×2 in which Wis the space between said spiral conductor patterns, and T is the conductor thickness of each of said spiral conductor patterns.
