PROBLEM TO BE SOLVED: To smooth a catheter surface, to prevent displacement of a reinforcing wire material, to prevent air bubbles from remaining in a catheter, and to compatibly achieve shape retention and flexibility.SOLUTION: The catheter with a reinforcing wire material 8 includes: an inner layer 6 an intermediate layer 7 laminated on the outer periphery of the inner layer 6 the reinforcing wire material 8 wound spirally along the intermediate layer 7 and an outer layer 9 laminated on the outer periphery of the intermediate layer 7 and the reinforcing wire material 8. The reinforcing wire material 8 is arranged so as to bite into the intermediate layer 7, and the catheter is formed.COPYRIGHT: (C)2013,JPO&INPIT【課題】カテーテル表面を平滑にし、補強線材の位置ズレを防止し、カテーテル内に気泡が残ることを防止し、保形性と可撓性を両立させる。【解決手段】補強線材8を有するカテーテルにおいて、内層6と、この内層6の外周に積層される中間層7と、この中間層7に沿って螺旋状に巻き付けられる補強線材8と、これら中間層7及び補強線材8の外周に積層される外層9とを備え、補強線材8を中間層7に食い込むように配置し、カテーテルを形成した。【選択図】図2
