コイルユニットおよびその製造方法

摘要

PROBLEM TO BE SOLVED: To provide a highly-weather resistant coil unit that is entirely covered with a high strength and high linear expansion resin.;SOLUTION: A coil unit includes a bobbin 20 having a groove 21 on a surface 22, a conducting wire 31 fitted into the groove 21 of the bobbin 20 to constitute a coil 30, and a resin cover 40 obtained by thermally-forming a resin sheet placed on the surface 22 of the bobbin 20 in which the conducting wire 31 is fitted so as to cover the surface 22 and side surfaces 24 of the bobbin 20 and the conducting wire 31, and the depth of the groove 21 is made substantially the same as the height of the conducting wire 31.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
