A catheter includes a hollow shaft, a mesh member, a front end tip, and a core wire. The mesh member has a tubular shape, has a base end joined to a front end of the hollow shaft, and is configured to expand and contract in a radial direction. The front end tip is joined to a front end of the mesh member. The core wire has a front end portion joined to the front end tip and extends inside the mesh member and inside the hollow shaft. A base end of the core wire is located on a base end side of the catheter relative to a base end of the hollow shaft. The front end portion of the core wire is formed with one or more holes, and a portion of the front end tip is disposed inside at least a portion of the one or more holes.
