ILLUMINATION DEVICE AND IMAGING DEVICE

An illumination device (4) that is applied to an imaging unit for imaging an object. The illumination device (4) comprises: an object cover (132) constituted from a member that can transmit light, the object cover (132) being provided so as to guide light from the object to the imaging unit in order to cause the imaging unit to image the object; and light sources (141, 142, 143) provided closer to the imaging unit than the object cover (132), for illuminating the object through the object cover (132). The light sources (141, 142, 143) are provided in a region farther out than an inversion region, in which a region defined by prescribed light beams included in luminous flux closer to the object than the object cover (132) is substantially inverted on the imaging unit side of the object cover (132), the luminous flux impinging on an imaging element (44) via imaging lenses (41a, 41b) from the object side in a state where the imaging lenses (41a, 41b) are focused on the object that contacts the object cover (132)
