PROBLEM TO BE SOLVED: To provide: a light-diffusible silicone rubber composition excellent in impact resistance, low temperature characteristics, and heat resistance, having an extremely wide usable temperature range, and compatibilizing the total light ray transmittance with the light diffusibility; and a molded form. SOLUTION: The light-diffusible silicone rubber composition is produced by adding 0.01 to 10 pts.mass of a light diffusing agent containing fine particles having an average particle diameter of 0.3 to 100μm of at least one type of polymer resin selected from a poly(meth)acrylic ester-based resin, a polystyrene-based resin, and a (meth)acrylic ester-styrene copolymer to 100 pts.mass of a silicone rubber compound having a total light ray transmittance of 70% or more as a cured sheet thereof having a thickness of 2 mm to disperse the light diffusing agent in the silicone rubber compound. The light-diffusible silicone rubber composition provides a cured form compatibilizing the total light ray transmittance with the light diffusibility by adding and dispersing a light diffusing agent containing polymer resin fine particles having an average particle diameter of 0.3 to 100μm in a predetermined amount to and in a silicone rubber compound providing a transparent or translucent cured form, and a light-diffusible rubber molded form (cured form) using the light-diffusible rubber composition has such characteristics as having flexibility of a silicone rubber and having an extremely wide usable temperature range.
