PROBLEM TO BE SOLVED: To provide an ink cartridge which has low interacting properties with ink, suppresses inferiority of printing quality in spite of environmental change, has transparency exhibiting high accuracy for detecting remaining amount of the ink, has a high rigidity that can suppress leakage of the ink by pressing, suppresses environmental obstruction, can be efficiently manufactured, and is inexpensive. SOLUTION: The ink cartridge 1 for an inkjet recording apparatus is formed of a material comprising a propylene homopolymer and a nucleating agent containing a specified organic phosphate compound. It is preferable that 0.01-1.0 pt.mass nucleating agent is incorporated in 100 pts.mass polypropylene, and hydrotalcite is incorporated as a neutralizing agent. COPYRIGHT: (C)2008,JPO&INPIT |
