    • The present invention provides a cellular potential measurement container that can measure a cellular potential with high accuracy while suppressing noise even when the number of the cells to be subjected to the measurement is increased. The cellular potential measurement container includes a first solution reservoir 14, a second solution reservoir 15, a partition substrate 18, a first electrode 27a, a second electrode 27b, a first measurement terminal 13a, and a second measurement terminal 13b. The first solution reservoir 14 and the second solution reservoir 15 are partitioned with the partition substrate 18, and the partition substrate 18 has a through hole 19. A first end of the through hole 19 is open toward the first solution reservoir 14 while a second end of the through hole 19 is open toward the second solution reservoir 15. The opening at the first end of the through hole 19 can hold a cell. The first electrode 27a is arranged so that a first solution can come into contact with the first electrode, and the second electrode 27b is arranged so that a second solution can come into contact with the second electrode. In the cellular potential measurement container with the above configuration, an electric signal amplifying device 16 further is provided, and the first measurement terminal 13a or the second measurement terminal 13b is connected to the first electrode 27a or the second electrode 27b via this electric signal amplifying device 16.
    • 本发明提供一种细胞电位测量容器,即使在要进行测量的细胞数量增加的同时,也可以以高精度测量细胞电位,同时抑制噪声。 细胞电位测量容器包括第一溶液储存器14,第二溶液储存器15,分隔基板18,第一电极27a,第二电极27b,第一测量端子13a和第二测量端子13b。 第一溶液储存器14和第二溶液储存器15被分隔基板18分隔开,分隔基板18具有通孔19.通孔19的第一端向第一溶液储存器14开口,而第二端 通孔19朝向第二溶液储存器15开口。通孔19的第一端处的开口可以容纳电池。 第一电极27a被布置成使得第一溶液可以与第一电极接触,并且第二电极27b被布置成使得第二溶液可以与第二电极接触。 在具有上述结构的细胞电位测量容器中,还设置有电信号放大装置16,并且第一测量端子13a或第二测量端子13b经由该电信号放大与第一电极27a或第二电极27b连接 设备16。
