ABSTRACT:
Provided is a heat-curable silicone composition containing: (A) an organopolysiloxane having at least one structure represented by the following general formula (2) within each molecule:wherein m represents an integer of 0, 1 or 2, R1represents a hydrogen atom, a phenyl group or a halogenated phenyl group, R2represents a hydrogen atom or a methyl group, R3represents an identical or different monovalent organic group having 1 to 10 carbon atoms, and R4represents an identical or different bivalent organic group having 1 to 10 carbon atoms; and (B) a quantity of an organic peroxide that is effective as a curing catalyst. The heat-curable silicon composition yields a cured product having excellent transparency and minimal discoloration over time. Also provided is a light emitting diode element having a material composed of the cured product.
