Abstract
A medical connector according to one embodiment of the present invention is provided with: a valve body which has a slit formed therein; a cylindrical outer housing which houses the valve body in the cylindrical shape thereof and retains the valve body therein; and a cylindrical inner housing which is inserted into the cylindrical shape of the outer housing so as to support an under surface of the valve body. A joint is formed between the valve body and the outer housing. The joint is positioned radially outward of the connector beyond the upper edge of the inner housing.

A medical connector comprising:
- a valve body in which a slit is formed;
- a cylindrical external housing that houses the valve body and holds the valve body;
- and
- a cylindrical internal housing that is inserted into the cylindrical external housing and supports a lower surface of the valve body,
- wherein a bonding portion is formed between the valve body and the external housing, and
- the bonding portion is positioned outside an upper end of the internal housing in a radial direction of the connector,
- wherein an outer circumferential surface of the valve body is bonded to an inner circumferential surface of the external housing by the bonding portion.
