A curable silicone resin composition is provided, including (A) a curable silicone resin-forming component of which a viscosity is 0.02 Pa·s or greater and 100 Pa·s or less, (B) surface-modified metal oxide particles which are surface-modified by a surface-modifying material having a reactive functional group and have an average primary particle diameter of 3 nm or more and 10 nm or less, and (C) a silicone compound having a reactive functional group of which a viscosity is less than the viscosity of the (A) component and is 0.01 Pa·s or greater and 1.0 Pa·s or less and having a content of 0.1% by mass or more and 15% by mass or less based on a total amount of the composition, in which a viscosity is 1.0 Pa·s or greater and 100 Pa·s or less.
