Abstract
A GRIN lens array of an embodiment has a structure for enabling a coupling face in which lens end faces of GRIN lenses are arranged, to be accurately polished so as to have a desired angle relative to optical axes of the GRIN lenses. The GRIN lens array has the GRIN lenses and a main body portion. The main body portion comprises a holding portion having a coupling face, and an edge portion having a reference face to be used as a reference in polishing of the coupling face. The respective thicknesses of the holding portion and the edge portion along the longitudinal direction of the GRIN lenses are set so as to form a step between the coupling face and the reference face.
