Abstract
A measuring container for measurement of impurity ions in a liquid includes: a first electrode; a first insulation film formed on the first electrode; a second insulation film formed apart from the first insulation film to create a space into which the liquid is to be sealed; a second electrode on which the second insulation film is formed, the second electrode being arranged to face the first electrode; and a seal material having an inlet through which the liquid is injected into the space, the seal material being configured to seal the space.
