The present invention provides a liquid ejecting apparatus capable of stably and efficiently coating a curable composition having a high property by raising the temperature of the curable composition to a temperature capable of discharging the liquid from the head in a short time without excessively heating the liquid. The liquid discharge device 1 includes a first tank 2 for storing a liquid composition, a head 3 for discharging the composition, first heating means 4 for heating the composition in the first tank 2, A first flow path 5 for supplying the composition from the first tank 2 to the head 3 and a second flow path 5 for supplying the composition passing through the first flow path 5 at a heating temperature higher than that of the first heating means 4 A second flow path 7 for refluxing the composition from the head 3 to the first tank 2 and a second pump 8 installed in the first flow path 5. The second heating means 6, And a first pump 9 installed in the second flow path 7. The temperature difference between the heating temperature by the second heating means 6 and the heating temperature by the first heating means 4 is 65 ° C Or less. |
