The present invention provides a two-dimensional left-handed metamaterial that functions as a two-dimensional electromagnetic wave propagation medium in which the equivalent permittivity and permeability of the medium are both negative, exhibits superior low-loss, broadband characteristics as a left-handed material, and has a simple constitution, enabling low-cost manufacture. The two-dimensional left-handed metamaterial is formed by disposing unit structures 10 constituted by a conductor regularly on a plane, the unit structure including: a columnar first prism, a central axis of which is oriented perpendicularly to the plane; a columnar second prism that has a central axis in an identical direction to the first prism and is disposed at a remove from the first prism in a central axis direction; and a connecting body for electrically connecting the first prism and the second prism to each other. The unit structures are disposed in identical positions in a perpendicular direction to the plane and so as not to contact another unit structure.
