1. A non-flammable heat-resistant resin composition, comprising:
(A) modified polyamideimide resin, (B) thermosetting resin and (C) organic phosphorus-based compound,
wherein a cured film, obtained from the non-flammable heat-resistant resin composition, exerts a storage elastic modulus of 700 MPa or less, a coefficient of thermal expansion of 5×10−3/K or less and an internal stress of 20 MPa or less, in a temperature range of 25 to 250° C., and
wherein the (A) modified polyamideimide resin is a modified polyamideimide resin that is obtained by allowing a mixture containing diimide dicarboxylic acid, represented by the following formula 1, formula 2 and formula 3 obtained through a reaction between a mixture of diamine having three or more aromatic rings, polyoxypropylene diamine and siloxane diamine, and trimellitic anhydride;
