The artificial blood vessel A comprises a front end wire ring 10<SMALLCAPS>1</SMALLCAPS>, a rear end wire ring 10<SMALLCAPS>2 </SMALLCAPS>arranged facing to the front end wire ring 10<SMALLCAPS>1</SMALLCAPS>, a tubular cover 7 which connects the end wire rings 10<SMALLCAPS>1</SMALLCAPS>, 10<SMALLCAPS>2</SMALLCAPS>, and a plurality of intermediate wire rings 12 arranged spaced apart from each other between the front end wire ring 10<SMALLCAPS>1 </SMALLCAPS>and the rear end wire ring 10<SMALLCAPS>2</SMALLCAPS>. Each of the front end wire ring 10<SMALLCAPS>1</SMALLCAPS>, the rear end wire ring 10<SMALLCAPS>2 </SMALLCAPS>and the intermediate wire rings 12 are given flexibly foldable elasticity. The circumference of the front end wire ring 10<SMALLCAPS>1 </SMALLCAPS>is equally divided into four by dividing points 41<SMALLCAPS>1</SMALLCAPS>, 42<SMALLCAPS>1</SMALLCAPS>, 43<SMALLCAPS>1</SMALLCAPS>, 44<SMALLCAPS>1</SMALLCAPS>. Hooking means 13 are formed for a front pull string to be passed through at the dividing points 41<SMALLCAPS>1</SMALLCAPS>, 43<SMALLCAPS>1</SMALLCAPS>. The circumference of the intermediate wire ring 12 is fixed to the tubular cover 7 by suturing or with adhesive at the positions 51<SMALLCAPS>3</SMALLCAPS>, 52<SMALLCAPS>3</SMALLCAPS>, 53<SMALLCAPS>3</SMALLCAPS>, 54<SMALLCAPS>3 </SMALLCAPS>which correspond to the midpoint 51<SMALLCAPS>1 </SMALLCAPS>between the dividing points 41<SMALLCAPS>1</SMALLCAPS>, 42<SMALLCAPS>1</SMALLCAPS>, the midpoint 52<SMALLCAPS>1 </SMALLCAPS>between the dividing points 42<SMALLCAPS>1</SMALLCAPS>, 43<SMALLCAPS>1</SMALLCAPS>, the midpoint 53<SMALLCAPS>1 </SMALLCAPS>between the dividing points 43<SMALLCAPS>1</SMALLCAPS>, 44<SMALLCAPS>1</SMALLCAPS>, and the midpoint 54<H
