HEAT DISSIPATION STRUCTURE

The present invention provides a heat dissipation structure which suppresses the positional displacement of a heat conduction member and with which it is possible to achieve a preferable heat dissipation function.The present invention is provided with: a display means 10 that has a display element 11 equipped with a display unit 11a for displaying prescribed information, a light source 12b serving as a heating electronic component for supplying illumination light to the display element 11, and a conductive frame body 16 for housing the display element 11 and the light source 12b; a heat conducting member 30 that transfers heat emitted by the light source 12b from the frame body 16 to a heat dissipation member 40; and a case member 50 that has an enclosure part 51 for enclosing the upper part 41a of the heat dissipation member 40 (heat dissipation part 41), wherein the enclosure part 51 encloses the upper part 41a of the heat dissipation part 41 in such a manner as to come into abutment with a non-contact part 31 of the heat conducting member 30 that is not in contact with the heat dissipation member 40.
