Antimicrobial catheter (1) comprises a body portion of a tubular made of a polymer material containing (3) Antibacterial agent (2), the antimicrobial agent (3) of the inner and outer surface near the main body (2) and characterized in that it is unevenly distributed in the vicinity. Also, a first step of adjusting the antimicrobial agent solution is prepared by dispersing the swelling organic solvent antimicrobial agent (3), the production method antimicrobial catheter (1) is dipped in an antimicrobial solution body portion (2) with, and is characterized in that it comprises a second step of impregnating the antibacterial agent (3) near the outer surface and the inner surface near the main body (2).抗菌性カテーテル(1)は、抗菌剤(3)を含有する高分子材料からなるチューブ状の本体部(2)を備え、抗菌剤(3)が本体部(2)の内表面近傍および外表面近傍に偏在していることを特徴とする。また、抗菌性カテーテル(1)の製造方法は、抗菌剤(3)を膨潤性有機溶媒中に分散させて抗菌剤溶液を調整する第1ステップと、本体部(2)を抗菌剤溶液に浸漬して、本体部(2)の内表面近傍および外表面近傍に抗菌剤(3)を含浸させる第2ステップとを含むことを特徴とする。
