PROBLEM TO BE SOLVED: To suppress an occurrence of eddy current and facilitate maintenance/replacement of each capacitor 4.SOLUTION: A capacitor device used for impedance matching of an induction heating apparatus or the like includes a first bus bar and a second bus bar which are laminated with an insulation plate 3 interposed therebetween, in which openings 11, 21 and seat portions 12, 22 are provided on each of the bus bars 1, 2 so as to be complementary to each other. The capacitor 4 at one side is attached so as to bridge a surface of the first bus bar 1 and the seat portion 22 of the second bus bar 22, and the capacitor 4 at the other side is attached so as to bridge a surface of the second bus bar 2 and the seat portion 12 of the first bus bar 12. A pair of terminal surfaces 43, 44 on a case bottom surface of the capacitor 4 are in contact with respective bus bars 1, 2 thereby being conductive. Therefore, a plurality of capacitors 4 are connected in parallel between the bus bars 1, 2. 【課題】うず電流の発生を抑制するとともに、各コンデンサ４の保守・交換を容易とする。【解決手段】誘導加熱装置等のインピーダンス整合に用いられるコンデンサ装置は、絶縁板３を挟んで積層した第１ブスバー１と第２ブスバー２とを有し、互いに相補の関係となるように、開口部１１，２１と座部１２，２２とが各ブスバー１，２に設けられる。一方の側のコンデンサ４は、第１ブスバー１の表面と第２ブスバー２の座部２２とに跨って取り付けられ、他方の側のコンデンサ４は、第２ブスバー２の表面と第１ブスバー１の座部１２とに跨って取り付けられる。コンデンサ４のケース底面における一対の端子面４３，４４が、各ブスバー１，２に接することで導通する。従って、複数のコンデンサ４がブスバー１，２の間に並列接続される。【選択図】図２
