An endoscope insertion portion of the invention comprises: a distal end portion first image pickup means for obtaining a first observation image, the first image pickup means being disposed to the distal end portion second image pickup means for obtaining a second observation image, the second image pickup means being disposed to the distal end portion a first object optical system for condensing photographing light incident on the first image pickup means, the first object optical system being located in the distal end portion a second object optical system for condensing photographing light incident on the second image pickup means, the second object optical system being located in the distal end portion and a plurality of illumination optical systems for irradiating light to a subject, the plurality of illumination optical systems being located in the distal end portion in a manner sandwiching each of the first object optical system and the second object optical system. The endoscope insertion portion thus can show enough of good observation performance by distributing a plurality of image pickup means with necessary amount of illumination light.
