A stent is disclosed that improves passing properties and an expansion force while securing a cross-sectional area of the stent and decreasing a decreasable diameter of the stent. The stent has linear struts, which form an outer periphery of a cylindrical shape and a link portion connecting the struts to each other, in which the struts of the cylindrical shape are mounted on an outer peripheral surface of a dilatable and deformable balloon. The stent has a plurality of strut cross-sectional portions in a cross section perpendicular to an axial direction of the struts of the cylindrical shape, the strut cross-sectional portions adjacent to each other in a circumferential direction of the struts have shapes different from each other, and surfaces of the strut cross-sectional portions adjacent to each other are in contact with each other when the struts are mounted on the outer peripheral surface of the balloon.
