PROBLEM TO BE SOLVED: To provide a reactor having a terminal board obtained by molding a bus bar. ! SOLUTION: The reactor comprises an annular core 1, coils 51a, 51b, a sensor 6 for detecting a state of the reactor, and a connector 62 of the sensor. Resin moldings 2, 3 are provided around the annular core 1. Bobbins 22a, 22b of the coils and coating parts 21, 31 of the core are integrally formed on the resin molding 2. An exposure part at which resin does not coat the bottom part of the core is formed on lower faces of the coating parts 21, 31. Bus bars 73a-73c are molded at an upper part of the coating part 21, and a terminal board 71c integrated with a holder 8 fixing a connector is arranged at the upper part of the coating part 21. An assembly of the resin moldings 2, 3 in which the annular core is embedded, and the coils 51a, 51b wound around the bobbins is housed in a metallic case. A gap is formed between the assembly and the case, and is filled with a filler. The exposure part at the core bottom par |
