Then, a metal plate (4) of the same shape cut to a size that is the same as or slightly larger than the diameter of this hole is press-fitted into the above-mentioned through hole so that the back side of the drawing board becomes a horizontal surface. , This substrate (1) and a part of the metal plate (4) are coated with an adhesive or masking ink whose main component is a thermosetting resin such as epoxy resin or phenol resin, or a photosensitive film is attached. By heating and curing the resin, the metal plate and a part of the substrate are firmly coated and bonded, and the drawing plates are integrated.

As shown in Fig. 4 above, the heat generated from the chip element mounted on the metal plate (4) is conducted through the metal plate, is quickly absorbed, and is dissipated from the back surface of the metal plate. This is K. In addition, as shown in Figure 4, the printed wiring board on which the chip element is mounted is mounted in a hole for mounting electronic components, so the entire printed wiring board on which the chip element is mounted becomes thinner. Moreover, it is also possible to achieve a smaller size than by directly mounting integrated circuit elements.
