In a catheter (1), since the thickness of an intermediate layer (29) is constant from a body (10a) to a distal end portion (10b), the adhesive strength (adhesiveness) between the intermediate layer (29) and an inner layer (24) is uniform from the body (10a) to the distal end portion (10b) of a catheter shaft (10). Therefore, when the catheter (1) is curved, the movement of a braid (26) caused by the curving of the catheter (1) can be uniformly suppressed from the body (10a) to the distal end portion (10b) that is adjacent thereto. Even if, when the catheter (1) is curved, a tensile stress (30a) towards a proximal end acts upon a first outer layer (28a) at the body (10a) and a tensile stress (30b) towards a distal end acts upon a second outer layer (28b) at the distal end portion (10b) adjacent to the body (10a), the first and second outer layers (28a, 28b) are caught by an uneven contour of the intermediate layer (29) by an anchor effect, so that it is possible to prevent peeling of the first and second outer layers (28a, 28b) from an intermediate layer (29).
