The present invention provides a medical connector and medical liquid storage vessel with which a connector can be removed by an easy operation and the possibility of unintentional removal of the connector can be minimized. This medical connector (100) has a mutually connected first connector section (10) and second connector section (20), and a release operation section (30) for releasing a state of locking of the second connector section (20) to the first connector section (10). The second connector section (20) is removed from the first connector section (10) by pulling the second connector section (20) apart from the first connector section (10) while also pressing against the release operation section (30) by a manual operation, in a direction opposite to the direction in which the first connector section (10) and second connector section (20) are pulled apart from one another.
