An optical printer head capable of minimizing production of a ghost by incidence of light reflected on a filter holding hole. Light emitted from a light source is reflected out of a maximum allowable incident angle to minimize generation of a ghost due to incidence of reflected light on a selfoc lens array while reducing a size of a filter holding hole for holding each of filters therein. Also, a peripheral surface of the filter holding hole may be rendered rough, to thereby provide a scattering surface, resulting in preventing repeated reflection of light emitted from the light source on the peripheral surface of the filter holding hole.
