PROBLEM TO BE SOLVED: To provide a communication apparatus housing box capable of reducing the internal temperature below the upper limit of a use environment temperature range of the communication apparatus, by using a resin box without incorporating a ventilator or a cooling device.SOLUTION: A communication apparatus housing box 1 to be installed outdoor while housing a communication apparatus includes a resin housing box body 2 having an opening for housing a communication apparatus 6, and a lid 3 capable of opening and closing the opening freely. At least the housing box body 2 has an absorptance, i.e., the ratio of energy amount absorbed from the light having a wavelength range of 380-1350 nm when irradiated with reference sun light, and the total energy amount of irradiance of reference sun light, of 4.4% or less.SELECTED DRAWING: Figure 2 |
