The present application discloses a bottle cap for a medicine bottle, such as a small bottle or vial or the like, in which the cap main body and a removable member made of the same metallic material are securely fixed to each other by cold pressure welding while forming therein pressed concave portions in an annular shape. Said cap main body and said removable member are provided within said pressed concave portions in the annular shape thereof with upwardly expanded portions. Thus, the present invention provides a good airtight cap which is easy to be manufactured and which can be heat-sterilized.
