Abstract
A circuit module mounting structure and a method for mounting an IC chip in the circuit module applicable to electronic equipment with a slim body. To increase radiation efficiency of the heat emitted from the IC chip, a heat conducting element including a plurality of thin plates is provided between a radiation plate of a heat sink unit and a surface of the IC chip. Further, the plurality of thin plates of the heat conducting element have sufficient flexibility to absorb stresses appearing at coupling portions of the elements due to dimensional tolerances of the elements.
