To provide a cap which is easily opened by a user whenever desired while being low in possibility of erroneous opening.

The dispensing cap (10) is such that is for mounting onto a container (100), and comprises a cap main body (20) having a dispensing port (23) and an opening/closing part (30) joined through a hinge to the main body for sealing up the dispensing port when closed. The cap has an elastic deformative part (26) which is formed entirely around the cap, being integral therewith, and the opening/closing part is partly exposed with the elastic deformative part deformed. With a stress applied to the exposed part (310), the opening/closing part is shifted from the state of closing to the state of opening, and the dispensing port is opened at least partly.
