Abstract
The invention provides an electric apparatus having a printed circuit board with an improved heat dissipation capacity, and, in particular, to provide an electric apparatus requiring plural printed circuit boards that has an improved heat dissipation efficiency and can be produced at a low cost. A main printed circuit boardand a sub boardare composite-molded, and the sub boardis formed at an area close to or immediately below a heat-generating electronic componentor a heat dissipation plate. Thus, by separating the sub boardoff the main printed circuit board, a hole serving as a ventilating hole is formed in the main printed circuit boardat the area close to or immediately below the heat-generating electronic componentor the heat dissipation plate
