摘要:
The invention relates to a printed wiring board (7) which includes at least one carbon resistor (3) formed across terminals (2a, 2b) of printed wiring circuit (2). A heat dissipating film layer (4) is formed at least on the carbon resistor (3). Thus, heat produced in the resistor (3) is effectively dissipated.
