The present invention is directed to suppress adhesion of a reagent to the periphery of an opening of a reagent container. The reagent container is a reagent container used for a sample measuring apparatus having a suction tube for suctioning a reagent, and includes a reagent, an upper surface part having an opening, a side surface part, and a bottom surface part that defines an internal space in which the reagent is stored, and a suction tube introducing part extending from the upper surface part to a position above the liquid level of the reagent to introduce the suction tube received from above the opening into the internal space.
