Abstract
A distal end barrel that holds a light guide bundle and an electronic image pickup unit inside a distal end portion is formed in such a manner that the distal end barrel is divided in a first distal end barrel arranged on the distal end side of the distal end portion and a second distal end barrel supported via the first distal end barrel so as not to be exposed at an outer surface of the distal end portion, the second distal end barrel holding the light guide bundle and the electronic image pickup unit, and the second distal end barrel includes a member having a thermal conductivity higher than the thermal conductivity of the first distal end barrel, thereby protecting the image pickup device from thermal damage without an increase in temperature of the outer surface of the distal end portion.
