PROBLEM TO BE SOLVED: To provide a manufacturing method of a surface light source capable of acquiring a surface light source having desired luminance, and a surface light source.SOLUTION: In a manufacturing method of a surface light source, light emission means is provided on a light emission surface of a tabular light guide body, and a light source is provided on a side surface. The light emission means uses a light guide body 10 equivalent to the light guide body. The light emission means 20 is provided with a uniform pattern on the light emission surface 14 of the light guide body 10. A light source 30 equivalent to the light source is provided on a light incident surface 15, and luminance emitting light from the light emission surface 14 of the light guide body 10 is measured, the pattern of the light emission means 20 is determined from the measured luminance, and the determined pattern is followed in the manufacturing method of a surface light source. |
