An intubation apparatus includes an inserting section that has an elongated shape and is to be inserted from a mouth of a subject toward a target site. An intubation tube is formed to extend along a longitudinal direction of the inserting section and is advanceable and retractable with respect to the inserting section. An imaging section is placed at a tip end of the inserting section and takes an in vivo image of the body of the subject. A detecting section detects a target site from the in vivo image based on a feature amount of the target site that is preset. A notifying section is disposed integrally with or separately from the intubation apparatus and notifies an operator who operates the inserting section. A notification controller controls the notifying section to notify of information relating to the target site of the subject based on a result of the detection.
