- the electrical components are substantially fixed only by the coating resin, it is difficult to secure a sufficient fixing force.
- the fixing force of the coating resin is reduced due to, for example, a decrease in the hardness of the coating resin in a high temperature region, and it has been difficult to wipe out the possibility that any of the desirable electrical component placement will occur.
- the thickness of the coating resin is substantially reduced to ensure a sufficient fixing force. There was a problem that it became difficult.

Since the resin frame is mounted on the substrate, the resin filled in the resin sealing space and solidified resin and the circuit components covered with the resin are securely fixed by the resin frame, and vibration is effectively prevented. .
- the thickness of the resin sealing space formed in the resin frame is compared with the case where the circuit component is substantially embedded and covered with only a single resin without using the resin frame in the prior art. Because it can be made very thin, it can minimize the effects of changes in the physical properties of the resin material (for example, a decrease in the hardness of the coating resin in the high temperature range).
- the members made of resin are excellent in workability and can be easily molded into various shapes, it is possible to easily manufacture a resin frame corresponding to the external shape of existing circuit components at a low cost.
