This endoscope is equipped with a fixed focus image pickup unit which is constructed of an objective optical system, and a solid state color image pickup device in which a color filter is arranged every pixel, the solid state image pickup device fulfilling a conditional expression (300 < IH/P < 550), and the objective optical system fulfilling a conditional expression (300 < Fl/P < 550) and a conditional expression (2400 × P < Fno. < 4200 × P), and is constructed with being equipped with the fixed focus image pickup unit in which an image pickup plane of the solid state image pickup device is arranged in a position where an MTF on an optical axis in a spatial frequency 1/(3 × P) of the objective optical system at 4 mm of object distance, and an MTF on the optical axis in a spatial frequency 1/(3 × P) at 50 mm of object distance become 10% or more together.
