The present invention provides a medical instrument having a blood contact portion formed of a hydrophobic material wherein a surface-active agent safe to a human body is deposited onto part or the entirety of the blood contact portion, ensuring that priming liquid is passed through the instrument to achieve priming without leaving fine bubbles adhered to the surface of the blood contact portion. The present invention also provides a method for fabricating a medical instrument, comprising the steps of assembling a medical instrument having a blood contact portion formed of a hydrophobic material, and contacting a liquid containing a surface-active agent safe to a human body to the blood contact portion, followed by drying, leaving the surface-active agent deposited to the surface of the blood contact portion so that the surface-active agent may be steadily and readily deposited to the blood contact portion of hydrophobic material.
