Abstract
A syringe assembly of a prefilled syringe includes a syringe cap. A tapered section of a second tubular section constituting this cap has, on an outer peripheral surface of the tapered section, a plurality of stepped sections continuously arranged along a center axis of a cover member, so as to gradually increase a protruding amount of the tapered section from an outer peripheral surface of an annular peripheral wall section toward a vicinity of an outer edge of an opening of a first tubular section.
