Abstract
The printed circuit board comprises a substrate 1 including a part loading portion 3 into which an electronic part 5 can be loaded, a plurality of contact terminals 2 which are respectively formed on one surface of the substrate 1 and the surfaces of which are exposed to the outside to provide external contacts, and openings 4 respectively formed in the other surface of the substrate 1 for insertion of bonding wires 6 which are used to connect the electronic part 5, which are to be loaded into the part loading portion 3 of the substrate 1, to its associated contact terminals 2. In the printed circuit board, each of the contact terminals 2 is formed of a metal foil 9 directly and closely attached to the substrate 1. This can prevent the lowered heat resistance of a printed circuit board which occurs when the metal foil, which is used to form the contact terminals 2, is bonded to the substrate 1 using an adhesive.
