Abstract
To provide a light guide member which has less components than conventional ones and has stable wavelength conversion efficiency; and a light source unit using the light guide member. A light guide member includes: a light guide plate; a receiving space formed in the light guide plate to face a light entrance plane; and a wavelength converting material placed in the receiving space. With the use of the light guide member, the number of components can be reduced and stable wavelength conversion efficiency can be achieved. Further, the production process can be facilitated and the production cost can be reduced.
