An underwater mobile inspection apparatus capable of inspecting an inspection object on a seafloor while cruising includes a cruising body configured to submerge under-water and cruise along the inspection object so as to not come into contact with the inspection object, a first movable arm provided on the cruising-body, and an inspection tool unit provided on the first movable arm and including at least one of an image-capturing camera for use in visually inspecting the inspection object and a device configured to inspect a wall thickness of the inspection object by using an ultrasonic wave. A controller is configured to, when the cruising-body cruises along the inspection object so as to not come into contact with the inspection object, operate the first movable arm to move the inspection tool unit, such that a positional relationship of the inspection tool unit with the inspection object becomes a predetermined target positional relationship.
