(Task) It is a thick film and can easily form a fine pattern, and has excellent properties of various films such as crack resistance, adhesion to substrates, electronic components, semiconductor devices, etc., especially to substrates used for circuit boards. A polymer compound containing a silicone skeleton capable of forming a highly reliable cured product layer (cured film) as a film for protecting electronic parts or a film for bonding to a substrate, a photocurable resin composition containing the polymer compound, and a photocurable dry film thereof, A method of forming a layered product and a pattern using these is provided. (Solving means) A silicone skeleton-containing polymer compound containing a silicone skeleton represented by the following formula (1) and having a weight average molecular weight of 3,000 to 500,000. |
