PURPOSE:To obtain a cap seal making it possible for a user to readily find the unsealing position at the time of unsealing after fitting to a vessel and capable of easy unsealing especially in the gloom by sticking a cutting tape which improves visibility by irradiation with light. CONSTITUTION:Both side edges of a heat shrinkable film 2 are overlapped and bonded and a cutting tape 3 is stuck to the bonded part of the resultant cylindrical body. The tape 3 is a tape of synthetic resin, etc., with a hologram of letters, a pattern, etc., formed on the surface and a metal such as Al vapor- deposited on the hologram. Both sides of the tape 3 are perforated parallel to the tape 3 to facilitate the cutting of the film 2 and the upper ends of the perforated parts 4 are notched 5 to obtain the objective cap seal 1. Since this seal 1 has the tape 3 with the hologram and the vapor-deposited Al, it is made possible for a user to find the cutting position with faint light even in the gloom and forgery cannot easily be carried out.
