A protector for a print head chip and an ink cartridge used by the same are provided. The protector () for a print head chip is independent from an ink cartridge () for storing ink. A contact surface () of the protector for a print head chip facing a print head contact is provided with contacts () for contacting corresponding contacts of the print head chip. The contact is connected to a memory () and sealed between the contacts of the print head chip and the protector for a print head chip. The protector has no structural relation to the ink cartridge, especially an ink supply port () and an ink supply needle of the ink cartridge. Therefore, even if the ink cartridge oscillates or moves horizontally to deviate from a centerline of the ink supply port, a communication effect is not influenced.
