Document Type and Number:
WIPO Patent Application WO/2021/010071
Kind Code:
A1
Abstract:
An inductor (1) comprises: a housing (2) made of an insulating material; and a conical coil (3) that is located inside the housing (2) and that is made of a coil conductor (4) that is wound in a spiral shape. The wound diameter of the conical coil (3) continuously expands. The interval measurement of the coil conductor (4) that is adjacent to the conical coil (3) in the winding axis direction continuously increases from the larger winding diameter to the smaller winding diameter of the conical coil (3). The stray capacitance generated around the coil conductor (4) continuously changes from the start to the end of winding of the conical coil (3).
