PROBLEM TO BE SOLVED: To provide a reagent container capable of suppressing arrival of a reagent at a container opening when the reagent is stirred.SOLUTION: The reagent container 1 includes a neck part 10 that is disposed in an upper part and has an opening 11, a reagent accommodation part 20 in which a reagent is accommodated, and an intermediate part 30 that connects the neck part 10 to the reagent accommodation part 20. The reagent accommodation part 20 includes a first extension part 21 in which the diameter of the inner surface increases from the inner bottom toward an upper part, and a contraction part 22 in which the diameter of the inner surface decreases from the first extension part 21 toward the upper part. The reagent accommodation part 20 or the intermediate part 30 has a second extension part 31 in which the diameter of the inner surface increases from the upper end of the contraction part 22 toward the upper part, and is formed so that a narrow part 40 located in a boundary between the contraction part 22 and second extension part 31 extends circumferentially on the container inner surface. |
