The medical instrument of the present invention is used for depositing a surfactant which is safe to a living body onto part or the whole of a blood contacting portion of the medical instrument having the blood contacting portion made of a hydrophobic material. The instrument of the present invention makes it possible to reliably conduct priming without causing fine bubbles to attach to the surface of the blood contacting portion when a liquid is caused to flow to said portion for the purpose of priming. Furthermore, the present invention relates to a method of producing a medical instrument wherein a surfactant can be reliably and easily attached to a blood contacting portion made of a hydrophobic material, and which comprises the steps of assembling a medical instrument having a blood contacting portion made of a hydrophobic material, bringing a liquid containing a surfactant which is safe to a living body into contact with the blood contacting portion, drying them and attaching the surfactant to the surface of the blood contacting portion.
