Kind Code: A1 The present invention relates to a moisture-curing combined photo-curing composition that has good handling, has excellent curability not only in UV irradiation sites but also in insufficient UV irradiation sites, and excellent electrical insulation of cured products, and a composition thereof. Providing an electronic circuit device including a cured film. And provision of the manufacturing method and storage method of the said composition. A (meth) acrylate oligomer (A) having an average of 1.5 or more (meth) acryloyl groups in one molecule and a diene-based or hydrogenated diene-based skeleton (A), a homopolymer A compound having one (meth) acryloyl group having a glass transition temperature of 50 ° C. or less, having no isocyanate-reactive group (B), a compound having two or more isocyanate groups (C), and an isocyanate reaction A photocuring composition containing a photopolymerization initiator (D) having no functional group, which is a moisture-curing combined photocuring composition for coating an electronic circuit, containing components (A) to (D) at a specific ratio.
