The present invention has a good filling property to recesses and through-holes, and has excellent curability to core parts, and thus there is no limitation on the selection of inorganic fine particles. It provides a photosensitive thermosetting paste composition that does not occur).n n n (A) Inorganic fine particles, (B) A binder polymer having a weight average molecular weight in the range of 3,000 to 300,000, (C) an ethylenically unsaturated bond-containing compound, (D) an optical radical generator, and (E) a thermal radical generator And what melt | dissolved the said (B) component in 1 or more types of the said (C) component is used. |
