PROBLEM TO BE SOLVED: To feed a power of a prescribed operating voltage to a CMOS image sensor despite the length of an inserting section (a voltage drop in a power supply line) in an endoscope apparatus having the CMOS image sensor for capturing an endoscopic image, at the distal end of the endoscope inserting section.SOLUTION: A regulator 122 is disposed near the CMOS image sensor 54 disposed at the distal end of the endoscope inserting section, so that the CMOS image sensor is stably fed with the power of the prescribed operating voltage. A regulator 120 is disposed at a location separated from the distal end of the endoscope inserting section. The regulator 120 feeds the regulator 122 with the power of substantially the same voltage to the prescribed operating voltage of the CMOS image sensor despite the length of the inserting section so as to prevent heat generation in the regulator 122. |
