PURPOSE: To simplify the wiring process and to improve the workability and the space factor for a magnetic head wiring device, by unifying the wirings of plural magnetic head into one via a flexible wiring board provided with a conduction part on a flexible film.

CONSTITUTION: Conduction parts 12 are formed on one sheet of a flexible film and connected to terminals 6 and 7 of a video record head 2 and erasion head 3 respectively to transmit electric signals. For a flexible circuit board 11, the connection part between heads 2 and 3 has the slack for margin. Therefore the azimuth of each head can be controlled independently. As a result, the wiring process is simplified and the workability and the space factor are improved.
