PROBLEM TO BE SOLVED: To provide a medical cap having good airtightness and re-sealability and improved for preventing a needle from being removed, and to provide a method for manufacturing the same.
SOLUTION: This method is for manufacturing a medical cap which has an elastic plug body having a plurality of steps on a peripheral side of a liquid contact surface, and an outer frame body having an upper frame part for holding the peripheral part of the elastic plug body from the upper surface side at the inner wall and a lower frame body for holding it from the lower surface side at the inner wall, and the upper frame body is formed by using a common mold and a first mold for having a site mounting the elastic plug body at the inner wall, and a needle insertion surface is turned downward in the upper frame body and the elastic plug body is mounted there, and a second mold can form a cavity for molding the lower frame body when it is combined with the common mold, and it is used for closing molds with the common mold, and a molten resin is injected in the cavity to form the lower frame body, and the lower frame body is cooled to contract and then the outer frame is formed under a condition of adding stress to a section where steps are arranged on the peripheral side to the elastic plug body.
