摘要： According to the electromagnetic wave measurement device of the present invention, an electromagnetic wave output device outputs an electromagnetic wave having a frequency equal to or more than 0.01 [THz] and equal to or less than 100 [THz] toward a device under test. An electromagnetic wave detector detects the electromagnetic wave which has transmitted through the device under test. A relative position changing unit changes a relative position of an intersection across which an optical path of the electromagnetic wave transmitting through the device under test and the device under test intersect with respect to the device under test. A characteristic value deriving unit derives a characteristic value of the electromagnetic wave based on a detection result of the electromagnetic wave detector while the characteristic value is associated with an assumed relative position which is the relative position if it is assumed that the electromagnetic wave is not refracted by the device under test. A first association correction unit changes the assumed relative position to an actual relative position, which is the relative position if the refraction of the electromagnetic wave by the device under test is considered, thereby associating the result derived by the characteristic value deriving unit with the actual relative position. A corrected characteristic value deriving unit that derives the characteristic value associated with a predetermined relative position based on an output from the first association correction unit.
