PROBLEM TO BE SOLVED: To solve the problems that a manufacturing process becomes complicated since a process for coating a coil 2 with coating material e.g. and a process of forming an air gap 4 by treating the coating material with heat are required conventionally, that the position of the coil 2 is shifted due to vibration or shock since the coil 2 is not fixed, and that defective conduction occurs since electrodes 6 are removed from the conductive member 5 while the air gap G repeats expansion and contraction due to thermal shock since there exists the air gap G between the conductive member 4 and the electrode 6. SOLUTION: The winding coil 10 is provided with a core 11 having a winding core 11A and guards 11B at both of its ends, a wire 12 wound on the winding core 11A, and the electrodes 13 and 13 which are formed on the lower surfaces of the respective guards 11B and 11B and with which both of the ends of the wire 12 are connected. On the respective upper surfaces of the wire 12 and the respective guards 11B, a hardening resin layer 14 including bubbles G is formed. COPYRIGHT: (C)2006,JPO&NCIPI
