A catheter includes a shaft having a first lumen inside thereof, an expansion/contraction portion that is disposed on a distal end portion of the shaft and is expandable and contractible in a radial direction, and an actuation portion that expands and contracts the expansion/contraction portion. The expansion/contraction portion has a fixed portion fixed to the shaft, a sliding portion capable of sliding in a longitudinal direction of the shaft on an outer peripheral face of the shaft, and a suspension portion extending in the longitudinal direction of the shaft that connects the fixed portion with the sliding portion. When the sliding portion is slid toward the fixed portion by the actuation portion, the suspension portion expands in a radial direction of the shaft.
