A projector capable of reliably reducing speckle noise is to be provided. A projector (1) includes a light modulation element which modulates laser light, and a projection optical system (5) on which light emitted from the light modulation element is incident. When the center coordinates of an illumination distribution of laser light in an exit pupil of the projection optical system (5) are x = 0 and y = 0, normalized illumination at each coordinate is P(x,y), and a calculation range of integration is r (mm), the value of EP determined from a specific numerical expression is set in a range according to the color of laser light.
