Circuit module

A circuit module comprising:

• a circuit board;
• a plurality of electronic components including at least one heat-generating electronic component, the plurality of electronic components constitute an electric circuit, and are spaced from each other on one or both sides of the circuit board;
• and
• a heat-dissipating member covering regions of a circuit board surface from one or both sides of the regions, the regions including at least regions around the plurality of electronic components including the heat-generating electronic component and one or more electronic components other than the heat-generating electronic component;
• wherein
• a surface of the heat-dissipating member facing the circuit board includes irregularities;
• an end surface of a protrusion in a facing surface of the heat-dissipating member is in contact with the circuit board surface between the plurality of electronic components, directly or with a heat-dissipation mediating member interposed therebetween;
• a wall surface of a recess in the facing surface of the heat-dissipating member is in surface-contact with the heat-generating electronic component within the recess, directly or with the heat-dissipation mediating member interposed therebetween, so that heat from the heat-generating electronic component and heat from the circuit board heated by the heat from the heat-generating electronic component are dissipated outside through the heat-dissipating member.
