Abstract
A liquid solder resist composition contains a carboxyl group-containing resin, a photopolymerizable compound containing at least one compound selected from a group consisting of a photopolymerizable monomer and a photopolymerizable prepolymer, a photopolymerization initiator, a titanium dioxide, and a compound having a cyclic ether skeleton. The titanium dioxide contains both of a rutile titanium dioxide manufactured by a sulfuric acid method and a rutile titanium dioxide manufactured by a chlorine method.
