Claims

[Scope of utility model registration request]

In a metal-based printed circuit board in which a wiring pattern is printed on a metal plate through an insulating layer, an insulating bushing that penetrates the metal plate and has a component glue insertion hole in the center is made of synthetic resin. A metal characterized in that it is formed integrally with a metal plate, and on the component mounting surface side of the metal plate, an end of the insulating bushing is integrally provided with a part for preventing the component from coming into contact with the metal plate. Base printed circuit board.
