<P>PROBLEM TO BE SOLVED: To enable to prevent a sealing substrate peeled from a light-emitting element with a heat-dissipating sheet, at changing of a deteriorated heat-dissipating sheet, in an organic EL light source unit. <P>SOLUTION: The organic EL light source unit 1 is provided with a light-emitting element 11, a power supply part 12, a front side and a rear side element cases 13a, 13b for retaining the light-emitting element 11 and the power supply part 12 and a heat dissipating sheet 14. The light-emitting element 11 includes a light-emitting layer 15, an element substrate 16, a sealing substrate 17 and a positive electrode 18a, as well as, a negative electrode 18b which are led out to an outer periphery of the sealing substrate 17. The element cases 13a, 13b include an opening 27 on a case wall 23, and have a structure for retaining an end part of at least one side of the sealing substrate 17. The heat-dissipating sheet 14 is arranged in the opening 27 in a plane view. When the deteriorated heat-dissipating sheet 14 is peeled from the sealing substrate 17, since the rear side element case 13b suppresses the force onto an end part of the sealing substrate 17, the sealing substrate 17 is prevented from peeling from the light-emitting element 11. <P>COPYRIGHT: (C)2011,JPO&INPIT |
