An imaging catheter includes an inner tube including a first lumen, a sensor unit disposed at a distal end portion of the inner tube and including: a reinforcing body that includes a shaft portion, a distal end support portion disposed at a distal end of the shaft portion, and a proximal end support portion disposed at a proximal end of the shaft portion, a diameter of each of the distal and proximal end support portions being greater than an outer diameter of the shaft portion, and a film sensor including transducers, the film sensor surrounding the reinforcing body, an outer tube surrounding the inner tube at a position on a proximal side of the sensor unit and including a second lumen, and a bonding portion formed of a resin bonding agent and joining the sensor unit to the inner and outer tubes.
