PROBLEM TO BE SOLVED: To provide a blood supply device which can always continuously supply pulsating blood flow. SOLUTION: A blood supply device is provided with a pulsation pump 10 for intermittently sending out blood by pulsation, a liquid containing section 20 for temporarily containing the blood sent out from the pulsation pump 10, and a check valve 23 for blocking reverse flow from the liquid containing section 20 to the pulsation pump 10, and the blood supply device is adapted to supply the blood from the pulsation pump 10 into a human body via the liquid containing section 20. The liquid containing section 20 is provided with a variable chamber 22 having an inner volume which changes due to elasticity of the variable chamber 22. A portion of the blood introduced into the liquid containing section in a contraction period of the pulsation pump 10 is contained in the variable chamber by expansion of the variable chamber 22, and the variable chamber is elastically contracted in an expansion period of the pulsation pump 10 to discharge the contained blood.
