PROBLEM TO BE SOLVED: To provide an illumination system capable of realizing a color image without a color wheel, and a projection system adopting the illumination system. SOLUTION: The illumination system includes at least one light emitting element 40 and a focusing lens 45 for focusing the beam radiated from the light emitting element 40, and a waveguide 50 having an incident surface 48 formed to be inclined by a predetermined angle, where the beam focused by the focusing lens 45 is made incident. The projection system includes the illumination system, a display element for forming the image by processing the beam made incident from the waveguide, and a projection lens unit for enlarging the image formed by the display element and projecting it to a screen side.
