Abstract: The temperature test apparatus includes a test antenna for measuring transmission and reception characteristics of a DUT, an anechoic box formed by a metal housing having an internal space, a heat insulating housing, a temperature control device that controls the temperature of a spatial region, and a measurement device that measures the transmission and reception characteristics of the DUT. The temperature control device and the heat insulating housing are connected to each other by a pipe 31 through which a gas for controlling the temperature of the spatial region passes and that goes through the metal housing. A portion 31A of the pipe from the metal housing to a predetermined position of the internal space is made of metal. A metal net portion 33 that blocks a pipeline 31Ae of a portion of the pipe 31 is provided.
