Summary:The present invention relates to an inkjet printing apparatus. The inkjet printing apparatus according to an embodiment comprises a stage, and an inkjet head positioned above the stage and including a plurality of nozzles through which ink including a plurality of particles is ejected. The inkjet head includes: a base part constituting a main body of the inkjet head; a discharge part disposed adjacent to the base part and disposed with the plurality of nozzles; and an internal flow path through which the ink is supplied between the base part and the discharge part. The base part includes a first surface in contact with the internal flow path, and at least a portion of the first surface has an inclination. A purpose of the present invention is to provide the inkjet printing apparatus for preventing precipitation of particles remaining in a print head unit, thereby making the number of particles in the ink uniform. 본 발명은 잉크젯 프린팅 장치에 관한 것이다. 일 실시예에 따른 잉크젯 프린팅 장치는 스테이지, 및 상기 스테이지 상부에 위치하고, 복수의 입자를 포함하는 잉크가 토출되는 복수의 노즐을 포함하는 잉크젯 헤드를 포함하며, 상기 잉크젯 헤드는, 상기 잉크젯 헤드의 본체를 구성하는 베이스부, 상기 베이스부와 이웃하여 배치되어 상기 복수의 노즐이 배치된 토출부, 및 상기 베이스부와 상기 토출부 사이에서 상기 잉크가 공급되는 내부 유로를 포함하고, 상기 베이스부는 상기 내부 유로와 접하는 제1 면을 포함하며, 상기 제1 면의 적어도 일부는 경사를 가진다.
