PRESSURE SENSITIVE ADHESION MEMBER AND LIGHT SOURCE DEVICE

PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesion member with excellent propagation efficiency of light irradiated from a light source, and a light source device provided with the pressure sensitive adhesion member. SOLUTION: The pressure sensitive adhesion member is constituted of a light propagation path provided with an adhesion surface with the light source and a light take-out surface facing it and formed of a pressure sensitive adhesive material, and a light reflective base material provided on the side face of the light propagation path. For the pressure sensitive adhesion member, the adhesion surface and light take-out surface of the light propagation path are roughly in a quadrilateral shape and the light reflective base material can be provided on both surfaces of at least one set of the surfaces facing each other among the side faces of the light propagation path. For the light source device, the pressure sensitive adhesion member is stuck to the light source so that the adhesion surface with the light source is brought into contact with the light source.
