PROBLEM TO BE SOLVED: To improve the hear dissipation characteristics to raise the light emitting intensity of a light emitting element such as LED and avoid deteriorating the element in a surface mounting IR communication module. SOLUTION: The surface mounting IR communication module 20 has an IR light emitting element 2 connected to a pair of inner connection electrodes 3, 4 on an insulation substrate 1 and also connected to a pair of outer connection electrodes 5, 6 through through-holes 7, 8, 9, 10. One outer connection electrode 5 is connected to a shield case 25 having a heat radiating action. This improves the heat dissipation characteristic of the device and shields from harmful electromagnetic waves to improve the communication reliability. |
