    • The present invnetion relates to a curable silicone composition comprises: (A) an organopolysiloxane represented by the average composition formula: R a SiO (4-a)/2 (in the formula, R is a halogen-substituted or unsubstituted monovalent hydrocarbon group, but from 0.1 to 2.1 mol% of the groups represented by R are alkenyl groups, and "a" is a number from 1.9 to 2.4); (B) an organopolysiloxane having an average of 2 silicon-bonded hydrogen atoms in a molecule, in an amount such that silicon-bonded hydrogen atoms in component (B) is from 0.1 to 3.0 moles relative to 1 mole of alkenyl groups in component (A); and (C) a platinum-based catalyst, wherein a content of component (C) is an amount such that a content of platinum atoms is from 10 to 100 ppm, in terms of mass units, relative to the present composition, and a content of each of sodium and potassium in the present composition is 3 ppm or less, in terms of mass units, relative to the present composition. The curable silicone composition forms a cured product having excellent heat resistance, and a cured product having excellent heat resistance.
