PROBLEM TO BE SOLVED: To provide a medical tool exhibiting an antiblocking effect while keeping the flexibility and transparency of at thermoplastic polymer. SOLUTION: This medical tool has an inner wall and/or an outer wall formed of a composite composed of a thermoplastic polymer and particles of polystyrene or methyl methacrylate. The thermoplastic polymer is favorably polyethylene, polypropylene, styrene-based elastomer, olefin-based elastomer, polyester-based elastomer, polyamide-based elastomer, polyurethane-based elastomer, or their mixture or polymer containing them as main components, and particles composed of polystyrene or polymethyl methacrylate are favorably globular particles of 5-70 μm diameter. |
