摘要：

PROBLEM TO BE SOLVED: To provide an endoscope device wherein a signal line outputting an image signal from an imaging means satisfies a safety standard as an explosion-proof structure, allowing securing of signal quality of the image signal regardless of a frequency characteristic of the image signal.

SOLUTION: This endoscope device 1 has: an insertion part inserted into a test object the imaging means 9 provided on a tip side of the insertion part, imaging the test object to output the image signal an image signal processing means 11 provided on a base end side to the imaging means 9, signal-processing the image signal input through the signal lines 20a, 20b and an imaging output barrier part 22 provided between the imaging means 9 and the image signal processing means 11, restricting electric energy to make the imaging means 9 side the explosion-proof structure. The imaging output barrier part 22 has a plurality of signal input side barrier circuits 25, 26 each transmitting a prescribed frequency area of the image signal as a transmission frequency component with a low attenuation amount compared to the other frequency area as the signal input side barrier circuits 25, 26 having the transmission frequency components different from each other.
