1. A light source device comprising:
a first laser light source which emits first laser light;
a second laser light source which emits second laser light;
a dividing part which divides the first laser light into first divided light and second divided light;
a light integration part which integrates the first divided light and the second laser light into one optical path;
a fluorescent substance part which receives the light integrated by the light integration part and emits fluorescent light;
a color light combining part which color-combines the second divided light and the fluorescent light into one optical path; and
a diffusion element which is provided on an optical path of the first laser light and diffuses the light,
wherein the diffusion element comprises:
a first lens array in which a plurality of first lens elements that divide the first laser light into a plurality of light fluxes are arranged; and
a second lens array in which a plurality of second lens elements that emit the light fluxes incident via the plurality of first lens elements toward an image formation plane are arranged,
wherein the first lens array is disposed on an incidence surface of the diffusion element,
wherein the second lens array is disposed on an emission surface of the diffusion element,
wherein at least two second lens elements among the plurality of second lens elements form light source images having different sizes in different regions on the image formation plane, and
wherein the diffusion element is disposed on an optical path of the second divided light between the first laser light source and the color light combining part.
