PROBLEM TO BE SOLVED: To provide a static induction equipment whose coil occupancy rate is large, whose coil serial electrostatic capacity is large, and whose insulation reliability on an impact voltage is excellent. SOLUTION: A disc coil 3 is constituted by winding a shield wire 2 by using a rectangular transition cable 1 whose cross-section is molded in an almost rectangular shape by packing flexible insulated materials 6 in recessed parts formed by displacing rectangular wires 4. Then, the plastic insulated materials 6 are thermohardened in a drying process after the coil is wound up. Thus, an electrostatic capacity between a transition cable 1 and the shield wire 2 and between the adjacent transition cables 1 can be increased. Even when the winding length of the shield wire is short, the serial electrostatic capacity of the whole coil can be increased. Therefore, it is possible to provide a static induction equipment whose coil occupancy rate is made high, and whose insulation reliability on an impact voltage is made excellent.
