Abstract: The purpose of the present invention is to provide a small electromagnetic wave detection apparatus. This electromagnetic wave detection apparatus has: a planar Luneburg lens, which is covered with metal plates facing each other, and which changes the output direction of electromagnetic waves corresponding to the input direction of the electromagnetic waves; and an electric field sensor electrically connected to the metal plates. The electric field sensor detects the electromagnetic waves outputted from the Luneburg lens, and outputs a detection signal having an intensity corresponding to the direction in which the electromagnetic waves have traveled thereto, and the level of the energy of the electromagnetic waves thus detected.
