Zusammenfassung:	To provide a medical tool having excellent slipperiness (especially piercing characteristics), and capable of exhibiting excellent antithrombogenicity.SOLUTION: A medical tool has a patchy structure including protrusions formed on a surface thereof and recesses formed on the surface. The protrusions include silicone, and the recesses are not substantially coated such that a surface of a base material is exposed. The protrusions have parts where a plurality of granular objects in plan view are randomly connected to form tortuous linear bodies, and the recesses surround peripheries of the protrusions in plan view to make the linear bodies of the protrusions relatively dispersed.SELECTED DRAWING: Figure 3 【課題】優れた滑り性（特に、刺通特性）を有し、かつ優れた抗血栓性を発揮できる医療器具を提供する。【解決手段】医療器具は、その表面に形成される凸部と、前記表面に形成される凹部とを含む斑状構造を有し、凸部は、シリコーンを含み、凹部は、実質的に被覆されておらず基材の表面が露出している。凸部は平面視で粒状のものがランダムに複数繋がって曲がりくねった線状体を形成している部分を有し、凹部は平面視でその凸部の周りを取り巻いて凸部の線状体を比較的分散させた状態にしている。【選択図】図３
