In folding binoculars with a built-in telephoto lens mechanism, the telephoto lens mechanism has support arms that are substantially parallel to each other connected to both ends of an objective lens support frame that is pivotally supported on the upper and lower lids, and the tips of these support arms are connected to each other. In between, the objective lens support frame elastically biased in an upright manner is horizontally suspended, and Fresnel lenses are fitted to the upper lid and the lower lid, respectively, so as to match the hollow portion within the telephoto lens mechanism.
