<P>PROBLEM TO BE SOLVED: To provide a transformer which can achieve reduction in size and height. <P>SOLUTION: A core 10 is rod-shaped. A brim part 32 is provided to both ends in the axial direction of a tubular part 31. A terminal electrode 41 is provided to a side end of the brim part 32. In each of coil devices 211 to 213, coils Np1, Np2, Ns1 and Nb1 are wound on the tubular part 31, and a terminal is connected to the terminal electrode 41. In each of the coil devices 211 to 213, the core 10 is inserted to an inner hole 33 of the tubular part 31 and the coil devices are integrated on the core 10. <P>COPYRIGHT: (C)2003,JPO |
