A positive-type photosensitive siloxane resin composition having not only excellent performance such as sensitivity, resolution, adhesive strength, permeability, and heat discoloration, but also suppressing gas release through excellent heat resistance and having a low moisture absorption rate. Provided. SOLUTION: A polystyrene-converted weight average obtained by hydrolysis and condensation polymerization of one or more reactive silanes represented by chemical formula 1 and one or more tetrafunctional reactive silanes represented by chemical formula 2 under a catalyst. A positive photosensitive siloxane resin composition comprising a siloxane copolymer having a molecular weight of 1,000 to 20,000; a 1,2-quinonediazide compound; and a solvent. (R1) nSi (R2) 4-n [Chemical formula 1], Si (R3) 4 [Chemical formula 2] [Selection figure] None |
