Abstract: An ink cassette capable of being mounted in a printer includes a supply bobbin, a winding bobbin, a plate member, and at least three engaging portions. The plate member is provided on an end part of the ink cassette on a near side of the ink cassette in a mounting direction of the ink cassette. The at least three engaging portions are provided in the plate member and engage with engaging portions of the printer when the ink cassette is mounted in the printer. In a case where the ink sheet, pulled out from the supply bobbin, and a print sheet are overlaid and pressed against a print head of the printer, ink is transferred from the ink sheet to the print sheet.
