The present invention relates to an anastomosis connector that is easy to insert into biological tubular tissue at the time of anastomosing first biological tubular tissue and second biological tubular tissue. This anastomosis connector (3) comprises: a wavy circumferential part (20) top-side narrow members (10A-1 to 10A-8) and bottom-side narrow members (10B-1 to 10B-8). The top-side narrow member (10A-1 to 10A-8) is connected to one of the top parts of the wavy circumferential part (20). The bottom-side narrow member (10B-1 to 10B-8) is connected to one of the bottom parts of the wavy circumferential part (20).
