Abstract

　線状光源装置（１００）は、透明樹脂製の導光部材（１２０）と、この導光部材（１２０）に対して光を出射する発光素子（２００）とを備えている。導光部材（１２０）は、柱状の本体部（１３０）と、この本体部（１３０）の両端に形成された第１の端部（１２１）と第２の端部（１２２）を備える。上記本体部（１３０）は、なめらかな鏡面状に形成された周面を有しており、その長手方向にわたる所定の帯状領域には、複数の凹部（１３１）または凸部（１３２）が形成されている。上記発光素子（２００）から出射した光は、上記本体部（１３０）の長手方向にわたって、上記本体部（１３０）の上記帯状領域と対向する領域から出射する構成とされている。上記凹部（１３１）または凸部（１３２）は、上記帯状領域の幅方向に直線状に延びている。
