PROBLEM TO BE SOLVED: To provide an ink filler of ink cartridge for printing in which an optimal quantity of ink can be replenished quickly. SOLUTION: A substantially tubular interconnecting core supporting section 2 is provided along the axial direction, entirely from the upper end to the lower end thereof, with a through hole 5 having diameter equal to or smaller than the outer diameter of an interconnecting core 1 having a channel 6 in the form of a longitudinal groove. The interconnecting core 1 can be inserted into the hole 5 and supported in place. Even if the interconnecting core 1 is inserted into the hole 5 between the upper and lower ends of the supporting section 2, the channel 6 serves as an opening communicating with the atmosphere thus ensuring an opening communicating with the atmosphere around the interconnecting core 1. |
