To provide a static magnetic wave device which can be made small and thin and easily mounted on electrical and electronic equipment.

This static magnetic device has a ferrimagnetic film 1, an RF signal feeder 2 and a magnetic field generator for applying a magnetic field to the ferrimagnetic film 1. The magnetic field generator is provided with a permanent magnet 6 and a set of yokes 4a and 4b magnetically connected to the permanent magnet 6 and facing each other across a gap, at least one insulating member 20 is fixed to at least one of the set of yokes, a conductor pattern 21 for a signal is formed on the surface of the insulating member 20, the conductor pattern 21 for a signal is electrically insulated from the set of the yokes 4a and 4b and also electrically connected to the RF signal feeder 2, and the conductor pattern is electrically connected to a circuit board before being subjected to surface mounting on the circuit board.
