| 摘要 |
The present invention provides a reliable print head with improved reliability which is inhibited from being damaged by possible cavitation in ink inside a bubbling chamber, as well as a printing apparatus using the print head. A plurality of ink supply paths through which the ink is supplied to the bubbling chamber are connected to the bubbling chamber. Communication positions where the plurality of ink supply paths communicate with the energy acting chamber are formed such that distanced from a heater formation surface of the communication positions are different from each other along a direction orthogonal to the heater formation surface.
