Abstract
A liquid outflow control unit used in an instrument for injecting a liquid such as a liquid medicine into a human body. It includes a plurality of separate partial members, at least one of which has a groove on a joined face thereof to form a small path through which a liquid passes.

The liquid flowing out of the exit is injected into the human body via a connection tube and a needle.
