PROBLEM TO BE SOLVED: To provide an endoscope system, which protects a light emitting element so as not to be damaged even in a single fault condition such that an electrode of an optical adapter part contacts a metal exterior part of an insertion part.
SOLUTION: The endoscope system 1 includes the optical adapter 8 that has a built-in LED 10 and is detachably installed on an end part of the insertion part 7. The endoscope system 1 also includes a light emitting element driving supply circuit 3 to drive the LED 10, a constant current circuit 6 to control the current running through the LED 10 at a predetermined value, and a current control circuit 4 interposed between the light emitting element driving supply circuit 3 and the LED 10 so as to control the current running through the LED 10 in the single fault condition of a signal line threaded through the insertion part of the endoscope.
