Abstract
A photoreactive resin composition having high sensitivity and causing less gelation, and methods of manufacturing a circuit board and a ceramic multilayer substrate having a high-resolution wiring pattern and via holes by a photolithography process using the photoreactive resin composition are described. The photoreactive resin composition contains an inorganic powder containing a polyvalent metal powder and/or a polyvalent metal oxide powder, an alkali-soluble first polymer having an ethylenically unsaturated double bond, a monomer having an ethylenically unsaturated double bond, a photoreaction initiator, an organic solvent, and a second polymer having a pyrrolidone ring in a side chain.
