A container closure of synthetic resin is for a container having a mouth-and-neck portion with an external thread on an outer periphery thereof and an engaging jaw portion positioned below the external thread. The container closure includes a body and a tamper evident skirt portion, and is configured to not be entirely separated from the mouth-and-neck portion of the container even after unsealing the container at the mouth-and-neck portion. At least in an angle region in which a protruding piece on a skirt wall of the body is present, an extending portion is defined at an engaging piece on the tamper evident skirt portion. When the container closure is mounted on the mouth-and-neck portion of the container, the extending portion of the container closure is positioned between the engaging jaw portion of the mouth-and-neck portion of the container and the tamper evident skirt portion of the container closure.
