よく組み立てることができる。 As described above, according to the present invention, a pair of loop-shaped printed coils wound approximately an integral number of times on one side of an annular insulating substrate are formed concentrically with the outer and inner ends of the coils close to each other. A rolled printed coil board is made, a through-connection rod is provided on the coil board at the inner and outer ends of the outer coil, a connection disk is provided at the inner end of the inner coil, and a connection cylinder is placed on the back side of the board facing this connection plate. By simply stacking a large number of coil plates in the same direction, the outer coils will be connected in parallel and the inner coils will be connected in series. The turn ratio of the inner (primary) coil and outer (secondary) coil is inversely proportional to the number of laminated sheets, so a laminated printed coil can be constructed, and this coil can be fitted to the legs of the EI or UI core to prevent leakage. Transformers with small inductance can be assembled efficiently.
