Abstract:
1. A method for mounting an optical member on a support substrate, the optical member having a plurality of luminous flux converters formed in a line on a surface of an optical substrate, and the support substrate having at least one positioning groove, said method comprising: bringing parts of side surfaces of at least two of a plurality of projecting portions into contact with the at least one positioning groove so as to position the optical member, wherein the projecting portions are formed for respective luminous flux converters so as to project, and wherein the plurality of projecting portions include edges that are partially along respective peripheries of the plurality of luminous flux converters; accommodating other projecting portions of the plurality of projecting portions, other than the at least two of the plurality of projecting portions, in a substrate groove formed in the support substrate, which substrate groove could be a groove of the at least one positioning groove or could be an additional groove, without contacting the other projecting portions with the substrate groove, and filling an adhesive agent between at least one part of side surfaces of the other projecting portions without contact with the substrate groove and the support substrate so as to adhere the optical member to the support substrate.
