A non-pneumatic tire includes: an inner annular portion; an outer annular portion; and a plurality of connecting portions connecting the inner and outer annular portions to each other. The first and second connecting portions are arrayed along a tire circumferential direction. The first and second connecting portions have a plate thickness smaller than a plate width and have a plate thickness direction oriented to the tire circumferential direction. When S is a length in the tire width direction and H is a height in a tire radial direction in the first and second connecting portions, an inclination angle K of a centerline of each plate width w of the first and second connecting portions to the tire width direction in intersecting portions of the first and second connecting portions when viewed from the tire circumferential direction satisfies a relationship of 30×(H/S)0.7≤K≤75×(H/S)0.7.
