摘要

PURPOSE: A paste coating head, a paste coating apparatus, and a paste coating method are provided to reduce the discharging amount of paste by supplying the paste from a main paste container to a sub-paste container and adjusting pressures in the sub-paste container. CONSTITUTION: A coating material container is composed of a main paste container(23) and a sub-paste container(24). Air pressure applying units are arranged at the main paste container and the sub-paste container. The flow path of a coating material is in connection with the sub-paste container. The flow path of the coating material is in connection with a nozzle(22) which discharges the coating material to a substrate. A coating material level sensor is arranged at the upper part of the sub-paste container.
