Inkjet application device and device for manufacturing battery

An inkjet application device, which is configured to apply a liquid material having particles dispersed therein through use of an inkjet head,

• the inkjet application device comprising a distribution flow path for the liquid material, the distribution flow path comprising a first flow channel configured to supply the liquid material pumped with a pump to a supply tank and a second flow channel configured to supply the liquid material in the supply tank to the inkjet head,
• wherein the supply tank accommodates a filter, the filter being configured to allow the particles in the liquid material to pass therethrough without allowing air bubbles in the liquid material, which are generated by the pumping of the pump, to pass therethrough, and
• wherein, when an inner diameter of the supply tank is represented by d2, and a vertical length of an internal space of the supply tank is represented by L1, L1/d2 is set to fall within a range of from 4 to 12.
