A sensor storage container includes: a lid configured to cover in an openable and closable manner an opening of an open-topped main body case that stores an elongated plate-like sensor lying flat; and a sensor ejecting tool configured to take the sensor out of the main body case. The sensor ejecting tool is elongated, and includes two ends, one end being linked to one of end sides of an opening portion of the main body case, and the other end being rotatable in a vertical direction between a bottom portion of the main body case and a position above the opening portion. A sensor adhesive portion at the other end of the sensor ejecting tool is provided with an adhesive face on a side of the sensor adhesive portion facing a bottom face of the main body case.
