Abstract
A two-chamber type combined container-syringe includes an outer tube () formed in a tubular shape having a uniform inner diameter about an axis (O) thereof throughout the axis direction and provided with a bypass groove () concaved from an inner circumferential surface in a portion in the axis direction, wherein the inner diameter of the outer tube () is 6.0 mm or more and 10.0 mm or less, the plurality of bypass grooves are formed in the circumferential direction of the axis at intervals, a cross-sectional area of the bypass groove perpendicular to the axis is 0.13% or more and 0.24% or less of an inner circumferential cross-sectional area of the outer tube perpendicular to the axis, and a depth of the bypass groove concaved from the inner circumferential surface is 2.7% or more and 3.8% or less of the inner diameter of the outer tube. As a result, solution can smoothly flow through the bypass groove, and an amount of solution remaining in the bypass groove can be reduced.
