A surface light source is provided which can press and attach a light source on a light-conductor plate in a manner not to cause a predetermined gap or more at between the light source and the light-conductor plate. Fixture-fit areas 49 are recessed on the both sides in the upper and lower surfaces of a light-source receiver 47 provided in a light-conductor plate 33, to provide snaps 50 projecting in the fixture-fit areas 49. Between the fixture-fit area 49 and the light-source receiver 47, formed are clamp steps 51 equal in depth to the fixture-fit area 49. Clamp steps 42 are recessed on the both sides in the upper and lower surfaces of the point light source 32 put in the light-source receiver 47. The metal fixture 52 is attached to the light-conductor plate 33 by engaging, on the snaps 50, the engaging holes 54 of the fit pieces 53 provided in the metal fixture 52. The clamp steps 51, 42 are clamped together by the upper and lower clamp pieces 55 provided in the metal fixture 52, thereby holding the point light source 32 with alignment thicknesswise of the light-conductor plate 33. Furthermore, by urging abutment pieces 56 of the elastically deflected metal fixture 52 on a backside of the point light source 32, the point light source 32 is urged on a light incident surface of the light-conductor plate 33. |
