PROBLEM TO BE SOLVED: To provide a planar emitter for offering a high and uniform brightness. SOLUTION: A planar emitter has a fusiform and light-quantity distribution LED 1 and a light conducting plate 3 formed of light conductive material for injecting an illumination light from a side wall face and emitting a parallel in-plane light flux from a rectangular emission plane 10, wherein first slopes 5, 5 gradually wider from the upper and lower long sides of the side wall face 4 to the outside and second slopes 6, 6 gradually narrower from the right and left short sides of the side wall face 4 to the outside and a shaped portion 7 encircling the LED 1 are molded into one unit. |
