Beschreibung
Zusammenfassung:	A heat-curable silicone resin composition for sealing optical semiconductors including: component (A): 100 parts by mass of a silicon compound expressed by Formula (1) below; and component (B): from 0.001 to 10 parts by mass of a condensation catalyst. (R1SiO3/2)a((R2)2SiO2/2)b((R3)3SiO1/2)c(SiO4/2)d(XO1/2)e (1) In this formula, R1, R2, and R3 are identical or differing monovalent organic groups, "X" is a hydrogen atom or a monovalent organic group, "a" is a positive number, "b" is 0 or a positive number, "c" is 0 or a positive number, "d" is 0 or a positive number, and "e" is 0 or a positive number; however "a" to "e" satisfy the following conditions: b/a is a number from 0 to 10, c/a is a number from 0 to 0.5, d/(a+b+c+d) is a number from 0 to 0.3, and e/(a+b+c+d) is a number from 0.01 to 1.5.
