Abstract: A cell transplantation device is used to place a graft containing cells into a target region in a living body. The cell transplantation device includes a needle extending in one direction, and a filter unit made of a fibrous member. The needle has a flow channel defined therein and an opening at the tip of the needle. The filter unit is disposed at an intermediate position in the flow channel and configured to retain a graft between the filter unit and the opening when a liquid material containing the graft enters the flow channel through the opening.
