摘要： PROBLEM TO BE SOLVED: To provide a dual-chamber type container/syringe in which a liquid agent can smoothly flow through bypass grooves and which can reduce an amount of the liquid agent remaining in the bypass grooves.SOLUTION: A dual-chamber type container/syringe includes an outer tube 10 formed in a tubular shape in which an inside diameter is uniform over an axis O direction around an axis O, and having, in a part of the axis O direction, bypass grooves 11a molded such that the bypass grooves 11a are recessed from the inner circumferential face; the inside diameter of the outer tube 10 is set to be 6.0 mm or more and 10.0 mm or less; the plurality of bypass grooves 11a are formed at intervals in a circumferential direction of the axis O; a cross section orthogonal to the axis O of the bypass grooves 11a is set to be 0.13% or more and 0.24% or less of an inner circumferential cross section orthogonal to the axis O of the outer tube 10; and a depth of the bypass groove 11a recessed from the inner circumferential face is set to be 2.7% or more and 3.8% or less of the inside diameter of the outer tube 10.
