Abstract: Provided herein is a curable silicone composition that has high optical transparency after being cured and that is in a putty form to be hand-mixable. A curable silicone composition contains: a specific organopolysiloxane as a component (1); a specific organohydrogenpolysiloxane as a component (2); a filler as a component (3); and a catalyst as a component (4). The difference between the refractive index of one of the components (1) to (3) that has the highest refractive index and the refractive index of one of the components (1) to (3) that has the lowest refractive index is 0.1000 or less. The complex viscosity of any of constituent compositions of the curable silicon composition before the curable silicone composition is cured is 10 Pa·s to 100000 Pa·s, as measured under predetermined measurement condition.
