<P>PROBLEM TO BE SOLVED: To provide a thermosetting composition capable of achieving excellent heat resistance, light transmission and luminance maintenance rate, and to provide a photosemiconductor device obtained by sealing an optical semiconductor element using the thermosetting composition. <P>SOLUTION: The thermosetting composition includes aluminosiloxane, a silicone oil containing silanol groups at both ends, an epoxy silicone and a silicone elastomer. The thermosetting composition is obtained by mixing a mixture of aluminosiloxane and the silicone oil containing silanol groups at both ends with the epoxy silicone and subsequently with the silicone elastomer, provided that the aluminosiloxane is obtained by reacting the silicone oil containing silanol groups at both ends and aluminum isopropoxide. The photosemiconductor device is obtained by sealing the optical semiconductor element using the thermosetting composition. <P>COPYRIGHT: (C)2010,JPO&INPIT |
