PROBLEM TO BE SOLVED: To provide an endoscope device capable of providing a scanned image as well as normal image and fluorescent image. SOLUTION: An OCT part 23 is provided on an endoscope device 1 capable of performing a normal observation and fluorescent observation. The OCT part 23 comprises a first wave guiding path 236 having a base end opposed to an SLD 231, a second wave guiding path 237 having a base end opposed to an optical detector 232, a coupler 238 for optically connecting these devices to each other, and a reference mirror 233 disposed at the tip of the second wave guiding path. A measurement light beam coming out of the tip of the first wave guiding path 236, reflected by a body cavity wall, and launched to the first wave guiding path 236 is interfered with a reference light beam coming out of the second wave guiding path 237, reflected by the reference mirror 233, and launched in the second wave guiding path 237 at the coupler 238, and these light beams are detected by an optical detector 232. Because the depth of a measured object can be changed by displacing the reference mirror 233, a scanned image of the body cavity wall can be provided.
