PROBLEM TO BE SOLVED: To provide a high-frequency reactor, suitable for a high frequency/large current (several kHz to several hundreds kHz, equal to or higher than several hundreds A), which is capable of cooling a core while preventing insulation performance deterioration of the coil caused by corona discharge in simple configuration and at low manufacturing cost.SOLUTION: The high-frequency reactor comprises a coil 10, a core 20 including a partitioned region 24 partitioned by a gap 21f; and a base 70 mechanically connected to the core 20 while being insulated by an insulator 60. The core 20 includes a plurality of core blocks 21 which are fixed while being spaced apart from each other by a conductive lower fixing plate 40 and an upper fixing plate 30. The lower fixing plate 40 fixes end portions of all the core blocks 21 closer to the base 70 and is mechanically connected to the base 70 via the insulator 60. The upper fixing plate 30 fixes end portions of all the core blocks 21 away from the base 70. The base 70 is mechanically connected to the lower fixing plate 40 via the insulator 60, and a distance D2 between the base 70 and the lower fixing plate 40 is larger than a width D1 of the gap 21f. |
