PROBLEM TO BE SOLVED: To provide an endoscopic device usable even in an environment surrounded with combustible gas or dust. SOLUTION: A control unit 3 constituting a scope unit 2 and an insertion part 4 are attached to a main unit 1 by a scope connector 5. An optical adapter 8 is attached to a front end of the insertion part 4. A CCD imaging device 31, HICs 32 and 33, and a thermistor 34 are attached to the front end of the insertion part 4. A liquid crystal module 36 is attached to the optical adapter 8. A barrier circuit 64 limits energy for circuits disposed in these components constituting the scope unit 2. When the barrier circuit 64 is provided in the scope connector 5, components extending forward beyond the position of the barrier circuit 64, namely, the control unit 3, the insertion part 4, and the optical adapter 8 are intrinsically safe and explosion-proof, and the main unit is usable even in a place where there is danger of explosion.
