To arrange a magnetic sensor and a magnet on a flexible printed board having flexibility, thereby separating it from a mother board or the like, and to improve installation accuracy of the magnetic sensor and the magnet.
The magnetic sensor-incorporating flexible printed board 1B (1) includes at least: a structure FPC1 where, on a first insulation layer RL1 formed with a conductor circuit 9 on one surface and formed with a first adhesive material layer 5 (AD1) on the other surface, via holes BH1 with the conductor circuit exposed from the other surface are formed, and conductive material 7 is included in the via holes; a magnetic sensor 3 electrically connected to the conductor circuit through the conductive material; and a magnet 4. The magnetic sensor and the magnet are included in the first adhesive material layer.
