Abstract
A method of producing a circuit board includes a step of providing a conductive paste including metal nano-particles at an insulating substrate, and a step of sintering the conductive paste so as to form a circuit conductor. In the sintering step, the conductive paste is sintered in a low-oxygen condition including alcohol such that the metal nano-particles are sintered.
