PROBLEM TO BE SOLVED: To use a food heating warmer at high illuminance by efficiently cooling LEDs to be easily incorporated in a thin structure. SOLUTION: A heat receiving plate 4 connectable to a metal base board 2 on which LEDs 1 are mounted and a heat radiating part 21 to which wind is blown from a blower part 16 are connected by a heat pipe 5. When the heat from the LEDs 1 reaches the heat receiving plate 4, the heat is immediately transferred to the heat radiating part 21 side by the heat pipe 5, and the heat is efficiently radiated with the wind from the blower part 16. Accordingly, the LEDs 1 are efficiently cooled without hindering the heat transfer to the heat radiating part 21. Furthermore, a module body 11 including the blower part 16 and the heat radiating part 21 and the heat receiving plate 4 can be conveniently disposed at separate positions.
