To prevent the unnecessary radiation or leakage of an electromagnetic wave in a terminal board for connecting a cable to a PC board used in electronic equipment or to a device by constituting an insulator with a composite magnetic body containing soft magnetic body powder and an organic binder.

A terminal board 1 has a base insulator 2 made of a composite magnetic body formed by kneading, dispersing soft magnetic body powder in an organic binder, and a screw 3 for fixing an electric wire from the outside through a terminal, and the screw 3 is connected by screwing in a screw hole formed in a flat plate of a base part embedded in the base insulator 2 of a pin terminal 4 to be connected to a printed board. The adjacent screw 3 and the base part 4a of the pin terminal 4 are integrally formed with the base insulator 2, and partitioned with a barrier rib 5 vertically formed in the base insulator 2. The barrier rib 5 is also made of the composite magnetic body formed by kneading, dispersing the soft magnetic body powder in the organic binder.
