A seal structure for removably sealing an ink outlet peripheral portion and an air communicating port peripheral portion of a replaceable ink cartridge to be removably connected with a recording means, for supplying ink into said recording means for recording an image on a recording medium, said replaceable ink cartridge having an ink cartridge body for storing the ink;

• an ink outlet and an air communicating port formed on said ink cartridge body;
• said ink outlet peripheral portion formed around said ink outlet;
• and said air communicating port peripheral portion formed around said air communicating port, said seal structure comprising:
• a seal portion for sealing an opening of said ink outlet and an opening of said air communicating port by sticking on said ink outlet peripheral portion and said air communicating port peripheral portion;
• and
• a handling portion for peeling off said seal structure, wherein
• said seal portion of said seal structure has a first seal portion for sealing said opening of said ink outlet;
• and a second seal portion for sealing said opening of said air communicating port, and
• said handling portion is constituted so as to easily transfer a force of peeling said sealing structure to be generated by said handling portion to said second seal portion that seals said opening of said air communicating port rather than said first seal portion that seals said opening of said ink outlet.
