ABSTRACT:
Provided are a printing head and an inkjet printing apparatus, which eject liquid droplets without leaving behind any bubble in each nozzle, thus having an enhanced durability. An ejection port of the printing head includes a first ejection port part communicating with the atmosphere and a second ejection port part having a cross-section orthogonal to an ejection direction being larger than a cross-section of the first ejection port part orthogonal to the ejection direction, and being formed between the energy effect chamber and the first ejection port part. In addition, the second ejection port part is formed to be eccentric to an electrothermal transducing element in an ink supply direction in which ink is supplied from an ink supplying port to the bubbling chamber.
