Laser light source unit

A laser light source unit configured to be able to irradiate, as combined light, laser light emitted from a plurality of laser diodes toward front of the laser light source unit, the laser light source unit comprising:

• a plurality of first condensing lenses configured to condense the laser light emitted from each of the plurality of laser diodes;
• a microlens array disposed on a front side of the laser light source unit with respect to the plurality of first condensing lenses;
• and
• a second condensing lens disposed on the front side of the laser light source unit with respect to the microlens array,
• wherein the microlens array and the second condensing lens are supported on a common lens holder,
• wherein the microlens array is supported on the lens holder via an array holder, and
• wherein a plurality of through-holes through which light emitted from the plurality of first condensing lenses passes is formed in the array holder.
