An objective of the present invention is to provide an irradiation apparatus capable of being miniaturized while enlarging an irradiation region. An irradiation apparatus includes an ultraviolet ray lamp (10) which serves as a linear light source, a main reflective plate (16) and a side reflective plate (18) each covering upper and end portions of the ultraviolet ray lamp (10), and a supplementary reflective plate (14) having a rectangular box shape and installed between the ultraviolet ray lamp (10) and a work (2). First reflective plates (40) are installed to each end portion (10A) of both sides of the ultraviolet ray lamp (10) between the supplementary reflective plate (14) and the ultraviolet ray lamp (10), where a lower end portion (40B) of the first reflective plate rather than an upper end portion (40A) is recessed toward the center (O) of the ultraviolet ray lamp (10). Thus, it is possible to dispose a stylobate portion (14A) of the supplementary reflective plate (14) near the end portion (10A) of the ultraviolet ray lamp (10) at the position of the first reflective plate (4). |
