A lens unit comprises a lens barrel, a pair of base plates, and iris blade, and a blade driving portion. The lens barrel holds a plurality of lenses, and has a first slit that extends in the circumferential direction. A pair of base plates each has an opening portion, and are stacked to structure a blade chamber, with a portion thereof protruding from the first slit, and is positioned so that the opening portions thereof are between the lenses. The iris blade is disposed in the blade chamber. A blade driving portion is secured to a portion of the pair of base plates, and drives the iris blade to open and close the opening portions in the iris blade.
