Claim:
1. An endoscope objective lens, comprising: a lens system with an object side and an image side, the lens system including a lens located most toward the image side, wherein a lens surface, of said lens, located closest to the image side of said lens system is a last lens surface of said lens system; an image sensor disposed on an image plane; and a reflective member that bends an optical path substantially at a right angle located between the last lens surface of the lens system and the image sensor, wherein, an effective diameter of the last lens surface is smaller than a size of the image sensor in a direction corresponding an optical path bending direction; and the endoscope objective lens satisfies a conditional expression given below: where: h1 is a distance in units of mm from a point where an optical axis of the lens system intersects with a reflection surface of the reflective member to the image plane; and V is an image height in units of mm on the image plane.
