    • An ink remaining amount detecting module (20) has a support substrate (21), an information storage element (22) provided on a first surface (21b) of the substrate (21), and external contact electrodes (24) provided on a second surface (21c) of the substrate (21). Two through-holes (21a) are formed in the substrate (21) so as to penetrate the substrate (21) from the first surface (21b) to the second surface (21c). A sealing structure (23) is provided on the first surface (21b) of the substrate (21) so as to cover the information storage element (22) and through-holes (21a). The sealing structure (23) is formed of a light transmissive member and is shaped like a prism. The ink remaining amount detecting module (20) is mounted on a cup portion (2) constituting a part of a housing of an ink tank so that the sealing structure (23) is exposed to an ink accommodating chamber (6).
    • 墨水剩余量检测模块(20)具有支撑基板(21),设置在基板(21)的第一表面(21b)上的信息存储元件(22)和设置在基板(21)上的外部接触电极 (21)的表面(21c)。 在基板(21)上形成有两个通孔(21a),以从第一表面(21b)穿过基板(21)到第二表面(21c)。 密封结构(23)设置在基板(21)的第一表面(21b)上,以覆盖信息存储元件(22)和通孔(21a)。 密封结构(23)由透光构件形成,并且形状类似于棱镜。 墨水剩余量检测模块(20)安装在构成墨盒的壳体的一部分的杯部(2)上,使得密封结构(23)暴露于墨水容纳室(6)。
