An inkjet printer comprises a platen roller (22) for holding a print medium (50), a print head (12) performing printing at a print position by ejecting ink from nozzle holes toward the print medium (50) held by the platen roller (22), a supporting member (18) for supporting the print head (12), and a pressing section for pressing the print head (12) against the supporting member (18). The supporting member (18) is disposed at a position facing opposite ends of the print head (12). At the time of printing, the print head (12) is pressed against the supporting member (18) and thus vibration of the print head (12) is suppressed.
