PROBLEM TO BE SOLVED: To provide an infrared ray transmission unit capable of reducing costs and a dimension without increasing the number of LEDs, widely expanding an infrared ray receiving range for an infrared ray signal, finely adjusting the direction of the infrared ray signal, and securing all-round covering. SOLUTION: This infrared ray transmission unit 4 comprises an infrared ray transmitting portion 6 for converting the information on control command of an air conditioner 2 from a controller 3 into the infrared ray signal S, and transmitting the infrared ray signal to the air conditioner 2 having an infrared ray receiving function, and the infrared ray transmitting portion 6 is composed of the plurality of LEDs 7 arranged in a line, and has an elastic locking function for lockably rotating the plurality of LEDs 7 by a prescribed angle.
