An ink cartridge (70) is mounted, when it is inserted in a predetermined insertion direction (R) to an abutting position, in a cartridge mounting portion (62) of a printing device (20). The ink cartridge (70) is equipped in a casing (71) with a plurality of low-voltage circuit terminals (111 to 113) and a plurality of high-voltage circuit terminals (114 and 115). The low-voltage circuit terminals (111 to 113) are arranged to form a column (A2) perpendicular to the insertion direction (R). The high-voltage circuit terminals (114 and 115) are perpendicular to the insertion direction (R) and are arranged to form a column (B2) closer than the column (A2) to the insertion direction (R).
