Abstract
A method of manufacturing a substrate includes applying solder resist ink containing a mixing resin of epoxy-based resin and acrylic-based resin on at least one surface of a substrate body to form a solder resist layer, and irradiating a predetermined portion of the solder resist layer with ultraviolet rays and controlling an amount of irradiation of the ultraviolet rays irradiated to the predetermined of the solder resist layer to form the predetermined portion in transmissivity that transmits light.
