It is possible to easily form a fine pattern with a thick film, and has good crack resistance and adhesion to a substrate, an electronic component, a semiconductor element, particularly a substrate used for a circuit board. A silicone skeleton-containing polymer compound that is capable of forming a cured layer (cured film) that is excellent in various film properties such as electrical properties, and has excellent reliability as a coating film for protecting electrical and electronic parts, and a coating film for substrate bonding, A photocurable resin composition containing a polymer compound, a photocurable dry film thereof, a laminate using these, and a pattern forming method are provided. A silicone skeleton-containing polymer compound containing a silicone skeleton and having a weight average molecular weight of 3,000 to 500,000 represented by the following formula (1).
