A method for producing a polyorganosiloxane resin composition, comprising: step (a1): mixing a thermally conductive filler having a unimodal particle size distribution with a surface treating agent containing siloxane; and step (b) ): the mixture of the thermally conductive filler and the surface treatment agent obtained in the above step (a1) is mixed with the polysiloxane resin, and the surface treatment agent contains the general formula (1) (in the formula, R 1 , R 2 , R 3 , X, a, b, c, R 4 , Y and d are the siloxane compounds represented by the definitions in the specification). |
