Document Type and Number:
Japanese Patent JP2021118338
Kind Code:
A
Abstract:
To provide a member for electric wire which can obtain an electric wire capable of effectively reducing loss in a high frequency easily and at a low cost, an electric wire using the member and coil, transformer and power conversion circuit device using the electric wire.SOLUTION: A spacer for electric wire is a spacer 20E, provided, on a surface thereof, with a plurality of recessed parts for maintaining a distance between conductor parts constituting an electric wire 100B within a certain range. The spacer 20E is constituted of insulation material. Under a state where the recessed parts of the surface maintain the conductor part at the recessed parts adjacent to each other, a distance D1 between the conductor parts adjacent to each other satisfies 170 μm≤D1≤540 μm.SELECTED DRAWING: Figure 2
