Abstract:
1. A circuit pattern forming method comprising: a first ejection step of ejecting large droplets of a circuit pattern forming liquid onto a substrate, by causing a liquid ejection head to scan the substrate, to form first dots of the liquid on the substrate with gaps between the first dots; a second ejection step of ejecting, from the liquid ejection head, in the same scan of the liquid ejection head as that of the first ejection step, after ejecting the large droplets and before the first dots formed on the substrate solidify, a small droplet, which is smaller in size than the large droplets, to form a second dot of the liquid between the first dots of the liquid already formed on the substrate, and thereby to form a liquid circuit pattern by mixing the first dots and the second dot together; and a fixing step of solidifying the liquid circuit pattern to form a circuit pattern on the substrate.
