Description of the Related Art Conventionally, a transformer formed by incorporating a magnetic core of this type into a coil bobbin and incorporating a core holder is shown in an exploded perspective view in FIG. 3 and an external perspective view in FIG. Insert the magnetic core 2 into the magnetic core assembling hole 4 of the coil bobbin 4.
c was installed from both directions of the coil bobbin 4, and then the two magnetic cores were held from above by the core holder 5 provided with spring plates on all four sides. However, the core holder 5 and the coil bobbin 4 are not fixed, and thus the core 2 Between the coil bobbin and the coil bobbin 4 and the backlash occurs, and when the core holder for holding the magnetic core is held and lifted, the core and the core holder are not fixed to the coil bobbin and therefore move upward, so that they are mounted on the substrate. However, there is a disadvantage that the height of the core holder from the substrate mounting surface is not constant.
