An entrance and exit way () of the communication path () is formed to be diagonally inclined with respect to a longitudinal axis of an insertion portion (). The first balloon groove () includes a shallow groove portion () that is formed to have a groove depth smaller than other portions in a circumferential direction of the distal end portion (), and the entrance and exit way () of the communication path () is provided in an internal region of the distal end portion () where the shallow groove portion () is formed.
