The invention provides a thermosetting resin composition and an insulating adhesive film thereof, the thermosetting resin composition comprises the following components in parts by weight: 30-70 parts of epoxy resin (A), 5-500 parts of modified spherical silica powder (B) and 30-70 parts of curing agent (C), the spherical silica powder comprises amino modified spherical silica powder, the D50 of the modified spherical silica powder is 0.1-2.0 [mu] m, and the D50 of the modified spherical silica powder is 0.1-2.0 [mu] m. The particle size distribution variable coefficient is greater than or equal to 35%. The modified spherical silica powder is used in an epoxy system, and the D50 range and the particle size distribution variable coefficient of the modified spherical silica powder are controlled, so that when the resin composition is used for an insulating adhesive film, the problem of high melt viscosity of a high filling system can be solved, low melt viscosity is obtained, and fine line ...
