PROBLEM TO BE SOLVED: To provide a thermosetting resin composition from which a cured product excellent in dimensional stability and an insulating layer excellent also in low-temperature meltability are obtained, and an interlayer adhesive film for obtaining an insulating layer.SOLUTION: The thermosetting resin composition contains a polyimide resin (A) having a biphenyl skeleton directly linked to a 5-membered cyclic imide skeleton and having a content of the bisphenyl skeleton of 20-45 mass% and a logarithmic viscosity of 0.2-0.8 dl/g, an epoxy resin (B), and an alkoxylated melamine resin (C). The interlayer adhesive film for a printed wiring board is obtained by applying the thermosetting resin composition onto a carrier film and drying it. |
