摘要： PROBLEM TO BE SOLVED: To obtain a reactor apparatus which has the high degree of freedom of raw-material selection and can also avoid the problem of burrs, and furthermore, can suppress the generation of an eddy current. SOLUTION: Each reactor core of the reactor apparatus has a pair of press surfaces (a-b plane) formed at the compression-processing of each reactor core, the edge of each press surface is plastically processed by pressure application, and furthermore, the edge is disposed in a direction wherein magnetic flux generated at applying a current to a coil 2 of the reactor apparatus does not pass through the press surface. Therefore, the generation of an eddy current can be suppressed even though the edge having a low insulating property exists on the press surface by the plastic processing.
