Abstract

PURPOSE:To make it possible to prevent the heating of the circuit conductors of a printed wiring board, by forming the circuit conductors on one or both surfaces of the board, and providing a heat radiating film at the circuit conductors. CONSTITUTION:Circuit conductors 11 are formed on one or both surfaces of a board 10. A heat radiating film 12 is deposited on the circuit conductor 11. The heat radiating film 12 is formed as follows: heat radiating paste, whose main component is metal such as copper and nickel or inorganic material such as ceramics of Al2O3 and the like, is applied during the manufacturing process of a printed wiring board 13 by an applying means such as silk printing; and the paste is hardened. Even if an insulating film is formed on the upper side of the circuit conductor 11 and the conductor is covered in the printed wiring board constituted in this way, heat can be radiated through the heat radiating film 12, which is formed on the upper side of the circuit conductor 11. Therefore, erroneous operation due to heating during the operation of the circuit conductors 11 can be prevented.
