Structure of the invention [Means for solving the problem] A fitting groove into which a partition plate attached to the terminal block is inserted is installed on the inside of the core case for the common mode choke coil. When winding the core case, it is removed to make it easier to wind the wire, and the partition plate used to separate the two windings is one resin terminal with a terminal attached to connect the ends of the winding lead wires. The terminals that are integrally attached to the base and connect the lead wire ends are formed on each of the two terminal blocks that sandwich the common mode York coil on the end face of the resin terminal block, and the terminals that connect the terminals of the lead wires are formed on each of the two terminal blocks that sandwich the common mode York coil on the end face of the resin terminal block. The Mode York coil is sandwiched from both sides of the coil by a resin terminal block fitted with a resin partition plate and another resin terminal block fitted with a fitting hole that fits into the shape of the tip of the partition plate.
The two resin terminal blocks are fitted and fixed through the partition plate and the fitting hole, and the lead wire terminals are connected to terminals provided on the terminal blocks, respectively, to form a common mode York coil for surface mounting.

On the inside of the resin case that houses the cylindrical core that forms the common mode chiyoke coil, a fitting groove is installed at the opposite position to allow the partition plate attached to the terminal block to pass through, forming a conventional common mode chiyoke coil. Unlike this type of core case, there is no partition plate, so winding the wires is easy. The terminal block has a fitting hole that fits into the partition plate,
By sandwiching the common mode chiyoke coil between two terminal blocks and fixing the common mode chiyoke coil to the terminal block by passing the partition plate through the fitting groove provided in the coil case, the common mode chiyoke coil and the terminal block can be connected. , the position of the terminal fixed to the conductor on the board is fixed.
