PROBLEM TO BE SOLVED: To provide a laminate for a white thermally conductive flexible substrate and a white thermally conductive polyimide film which are excellent in a heat radiation characteristic, high reflectance and a dimensional change ratio and which have excellent tear resistance even in a thin film form. SOLUTION: A polyimide resin layer constituting the laminate for the flexible substrate or the thermally conductive polyimide film is a layer having a filler-containing polyimide resin layer (i) containing a thermally conductive filler in a range of 20 to 65 wt.% in a polyimide resin containing 50 to 100 mol% of a structural unit deriving from 2,2'-bis (trifluoromethyl)-4,4'-diaminobiphenyl and aromatic tetracarboxylic acid dianhydride.
