A syringe with needle comprising: an outer cylinder including an outer cylinder body part and a needle fixing part provided at a distal end part of the outer cylinder body part; an injection needle having a puncturing needle tip at a distal end, a proximal end part of the injection needle configured to be fixed to the needle fixing part of the outer cylinder; and a gasket configured to be housed in the outer cylinder and capable of sliding within the outer cylinder in a liquid-tight state, wherein the injection needle is such a tapered part holding injection needle that a piercing part having the puncturing needle tip has an outer diameter of 0.42 mm or less and has a thickness of 0.1 mm or less, and extending by a predetermined length with substantially the same outer diameter, a tapered part extending from a proximal end of the piercing part in a proximal direction and expanded in diameter in a tapered manner in the proximal direction; and the proximal end part extending from a proximal end of the tapered part with substantially the same outer diameter in the proximal direction, a lubricant is not applied to an inner surface of the outer cylinder, the gasket includes a gasket body made of an elastic body, wherein the inner diameter of the piercing part is equal to or greater than 0.05 mm, wherein an outer diameter of a proximal end of the tapered part holding injection needle is greater than the outer diameter of the piercing part by 0.15 mm or more, a length of the proximal end part is 3.0 to 12.0 mm, an outer diameter of a proximal end of the proximal end part is equal to or greater than 0.40 mm, an inner diameter of a proximal end of the proximal end part is equal to or greater than 0.30 mm, and a ratio of the inner diameter of the piercing part to the inner diameter of the proximal end of the proximal end part is 1:1.5 to 1:2.5, characterised in that the gasket further includes a soft coating provided on at least a portion that comes into contact with the inner surface of the outer cylinder, the soft coating having a liquid-tight sliding property with respect to the inner surface of the outer cylinder, whereby a portion including the tapered part is fixed to the injection needle attaching part. an outer cylinder including an outer cylinder body part and a needle fixing part provided at a distal end part of the outer cylinder body part; an injection needle having a puncturing needle tip at a distal end, a proximal end part of the injection needle configured to be fixed to the needle fixing part of the outer cylinder; and a gasket configured to be housed in the outer cylinder and capable of sliding within the outer cylinder in a liquid-tight state, wherein the injection needle is such a tapered part holding injection needle that a piercing part having the puncturing needle tip has an outer diameter of 0.42 mm or less and has a thickness of 0.1 mm or less, and extending by a predetermined length with substantially the same outer diameter, a tapered part extending from a proximal end of the piercing part in a proximal direction and expanded in diameter in a tapered manner in the proximal direction; and the proximal end part extending from a proximal end of the tapered part with substantially the same outer diameter in the proximal direction, a lubricant is not applied to an inner surface of the outer cylinder, the gasket includes a gasket body made of an elastic body, wherein the inner diameter of the piercing part is equal to or greater than 0.05 mm, wherein an outer diameter of a proximal end of the tapered part holding injection needle is greater than the outer diameter of the piercing part by 0.15 mm or more, a length of the proximal end part is 3.0 to 12.0 mm, an outer diameter of a proximal end of the proximal end part is equal to or greater than 0.40 mm, an inner diameter of a proximal end of the proximal end part is equal to or greater than 0.30 mm, and a ratio of the inner diameter of the piercing part to the inner diameter of the proximal end of the proximal end part is 1:1.5 to 1:2.5, characterised in that the gasket further includes a soft coating provided on at least a portion that comes into contact with the inner surface of the outer cylinder, the soft coating having a liquid-tight sliding property with respect to the inner surface of the outer cylinder, whereby a portion including the tapered part is fixed to the injection needle attaching part.
