The object is to provide a printing device with a superior gas barrier property in an ink supplying passage. As a solution therefor, an ink supplying unit (10) of an inkjet printing device (100) includes a pressure chamber (11) connected to a supplying passage (21). The pressure chamber (11) is formed of a resin material having a superior gas barrier property, and can be warped by a biasing force in a direction along which a distance between opposing inner walls thereof is increased so as to be able to set an inside of the ink supplying passage to a negative pressure. |
