Abstract:
1. An ink cartridge comprising a main body, a cover member, and an insulating seal member, which are components for constituting the ink cartridge for an inkjet printer, wherein the main body and the cover member are bonded to each other with an electrically-disbonding adhesive having a characteristic of causing a bond dissociation with a passage of an electric current so as to form an ink storing section, the main body has a first electrode being arranged at a portion where the main body is in contact with the electrically-disbonding adhesive for passing the electric current through the electrically-disbonding adhesive, the cover member has a second electrode being arranged at a portion where the cover member is in contact with the electrically-disbonding adhesive for passing the electric current through the electrically-disbonding adhesive, the seal member is arranged in the vicinity of a bonding portion where the main body and the cover member are bonded to each other so as to keep the cartridge liquidtight, and so as to prevent an ink stored in the storing section from being in contact with the first and the second electrodes.
