PROBLEM TO BE SOLVED: To provide a pattern formation method for forming a high-density/high-definition pattern in a short period, and to provide a circuit substrate. SOLUTION: A green sheet 4G is heated by a rubber heater H provided on a stage 24. The green sheet 4G is subjected to heating control so as to make it reach a temperature higher than or equal to the temperature of a functional liquid during discharge and lower than or equal to the liquid-droplet boiling point. Under this heated condition, liquid-droplets are discharged onto the green sheet 4G from a liquid-droplet discharge head 30. The liquid-droplets that land on the green sheet 4G are dried quickly, without bumping. COPYRIGHT: (C)2008,JPO&INPIT
