An image capture device 1001 captures an image by using a terahertz wave and includes a generating unit 112 that includes a plurality of generation elements each of which generates the terahertz wave and rests on a resting plane 117, an irradiation optical system 111 that irradiates an object with the terahertz wave, an imaging optical system 101 that images the terahertz wave that is reflected from the object, and a sensor 102 that includes pixels. The plurality of generation elements include at least a first generation element 113 and a second generation element 114 that have different angles of radiation to the object. There is an overlap region in which a region of radiation of a first terahertz wave 156 from the first generation element to the object overlaps a region of radiation of a second terahertz wave 157 from the second generation element to the object.
