A syringe container comprising: a cylindrical syringe including a distal end portion having a discharge opening for discharging a filled liquid, a proximal end portion located at an opposite side of the distal end portion, and a side peripheral section continuing to the distal end portion and the proximal end portion; an attachment member attached to the distal end portion and having an outer radius larger than an outer radius of the side peripheral section; a container body including a bottom portion in a bottom end and a peripheral wall portion extending upward from a periphery of the bottom portion; and a syringe holding section configured to be placed within the container body so as to face the bottom portion and including a through-hole in which the syringe is vertically inserted and holds the syringe by inserting the syringe in the through-hole, wherein an inner peripheral surface forming the through-hole has an upper end having a radius larger than an outer radius of the attachment member, a bottom end having a radius larger than the radius of the upper end, and a tapered section having a diameter that is reduced from the bottom end toward an upward direction, characterized in that a tapered distance between a radius of the bottom end of the tapered section and a radius of the upper end of the tapered section is equal to or larger than a syringe radius difference between the outer radius of the attachment member and the outer radius of the side peripheral section, and the syringe radius difference is in a range of 1 to 2 mm and a taper angle (θ) of the tapered section is in a range of 5 to 30 degrees. a cylindrical syringe including a distal end portion having a discharge opening for discharging a filled liquid, a proximal end portion located at an opposite side of the distal end portion, and a side peripheral section continuing to the distal end portion and the proximal end portion; an attachment member attached to the distal end portion and having an outer radius larger than an outer radius of the side peripheral section; a container body including a bottom portion in a bottom end and a peripheral wall portion extending upward from a periphery of the bottom portion; and a syringe holding section configured to be placed within the container body so as to face the bottom portion and including a through-hole in which the syringe is vertically inserted and holds the syringe by inserting the syringe in the through-hole, wherein an inner peripheral surface forming the through-hole has an upper end having a radius larger than an outer radius of the attachment member, a bottom end having a radius larger than the radius of the upper end, and a tapered section having a diameter that is reduced from the bottom end toward an upward direction, characterized in that a tapered distance between a radius of the bottom end of the tapered section and a radius of the upper end of the tapered section is equal to or larger than a syringe radius difference between the outer radius of the attachment member and the outer radius of the side peripheral section, and the syringe radius difference is in a range of 1 to 2 mm and a taper angle (θ) of the tapered section is in a range of 5 to 30 degrees.
