PROBLEM TO BE SOLVED: To provide a guide catheter where a tube and a wire are unlikely to separate.SOLUTION: A guide catheter includes: a resin tube 11； a metallic pipe 16 fitted inside the tube 11； and a metallic wire 17 welded onto an outer peripheral surface 16a of the pipe 16. The pipe 16 has: a proximal end surface 16e connecting the outer peripheral surface 16a of the pipe 16 and an inner peripheral surface 16b of the pipe 16 on a proximal end 16d side of the pipe 16； and a most proximal end part 16f positioned nearer on the proximal end side than other parts of the proximal end surface 16e in an axial direction of the pipe 16 of the proximal end surface 16e. When viewed along a central axis of the pipe 16, a welding area of the wire 17 with respect to the pipe 16 is at a position overlapping the outer peripheral surface 16a adjacent to the most proximal end part 16f of the pipe 16. When viewed from a direction orthogonal to the central axis of the pipe 16, a proximal end of the welding area is at a position away from the most proximal end part 16f of the pipe 16 toward an end 16c side.SELECTED DRAWING: Figure 5【課題】チューブとワイヤとが離断しにくいガイドカテーテルを提供すること。【解決手段】樹脂製のチューブ１１と、チューブ１１内に取り付けられた金属製のパイプ１６と、パイプ１６の外周面１６ａに溶接された金属製のワイヤ１７とを備え、パイプ１６は、パイプ１６の基端１６ｄ側においてパイプ１６の外周面１６ａとパイプ１６の内周面１６ｂとを繋ぐ基端面１６ｅと、基端面１６ｅのうちパイプ１６の軸方向において基端面１６ｅの他の部位よりも基端側に位置する最基端部１６ｆとを有し、パイプ１６の中心軸に沿って見たときに、パイプ１６に対するワイヤ１７の溶接領域は、パイプ１６の最基端部１６ｆと隣接する外周面１６ａに重なる位置にあり、パイプ１６の中心軸と直交する方向から見たときに、溶接領域の基端は、パイプ１６の最基端部１６ｆから先端１６ｃ側に離れた位置にある。【選択図】図５
