The organosiloxane-based high molecular compound of the present invention has a repeating unit represented by the following formula (1) and has a weight average molecular weight of 1,000 to 500,000, thereby producing a photocurable resin composition which can be exposed to a wide wavelength of light. Can:n n n n n n n n [R 1 ~R 4 is a monovalent hydrocarbon group, n is an integer of 1-2000, X has the formulan n n n n n n n (Me is a methyl group), and R 5 is the following formulan n n n n n n n R 'is a hydrogen atom or a methyl group and R "is a divalent hydrocarbon group, which may be the same or different acrylic functional organic groups. |
