The bendable catheter (1) includes a flexible tubular main tube (2) a bendable part (3) having a longitudinal axis and an internal space formed along the longitudinal axis, a bendable part (3) that is arranged at the distal end of the flexible tubular main tube and is capable of being bent and a bending manipulation wire (8) that allows the bendable part to bend. The main tube (2) has a first lumen (2c) and a second lumen (2d). The bendable part (3) has a tubular bendable tube fixed to the distal end of the main tube (2) and being more flexible than the main tube (2), the first coil (6) having a distal end arranged within the bendable tube (5) and a proximal end provided with an inner cavity communicating with the first lumen (2c), and fixed to at least one of the main tube (2) and the bendable tube (5), and the second coil (7) having a central axis extending parallel to a central axis of the first coil (6), provided adjacent to the first coil (6) in a space formed between the bendable part (3) and the first coil (6), and fixed to an inner surface of the bendable tube (5). The bending manipulation wire (8) is inserted through an inner cavity of the second coil (7) and the second lumen (2d), and a distal end of the bending manipulation wire (8) is fixed to at least one of the bendable tube (5), the first coil (6), and the second coil (7).
