The problem to be solved by the present invention is to provide a photocurable resin composition containing a silicone skeleton-containing polymer, a photo-curable resin composition containing the polymer compound, a photo-curable dry film, a laminate using the same, and a patterning method. The silicone skeleton polymer can easily form a fine pattern with a thick film and can form a cured productlayer having excellent reliability as a film for protecting an electric / electronic part, a film for bonding a substrate. Resistance to cracking, and joint sealing property of a substrate, an electronic component, or a semiconductor element, especially a base material used in a circuit substrate, and other various film characteristics are excellent. A technical scheme of a problem the inventionsolved is a silicone skeleton-containing polymer represented by the following formula (1), comprising a silicone skeleton and having weight average molecular weight of 3,000 to 500,000.
