PURPOSE: To prevent an end disconnection, deformation of a bobbin and the crank of a terminal conductor due to a construction of connecting the end of a winding coil by making a construction of winding the end of the winding coil at plural positions of the terminal conductor along plural notches formed on the terminal conductor.

CONSTITUTION: Terminal conductors 4, 4 are long and slender plates with a rectangular section at all positions and on both side os nearly center of each conductor, V-shape notches 4a, 4a are formed and similar V-shape notches 4b, 4b are also formed on both sides of the adjacent position to the end of a bigger portion 3a. The both ends 5a, 5a of a winding coil 5 wound around a cylinder are wound around the terminal conductors 4, 4 at two positions along the notches 4a, 4a, 4b, 4b, the wound portion of the end 5a is soldered at the notches 4a, 4a by soldering of a portion indicated by oblique lines and connected to the terminal conductor 4. This construction separates the portion between the winding at the notch 4b of the end 5a and the winding coil 5 from the soldered portion not to be affected by the high temperature of the soldering and not to be made thinner.
