The stent comprises a tubular body comprising a plurality of ring units arranged in the axis direction and bridged by a connecting element. Each of the units comprises a plurality of cells connected with each other, each of the cells having a U-shaped form comprising two linear parts and a circular arc part therebetween, and opening toward one end. The ring units comprise first and second units alternatively arranged and the oppositely disposed cells of the first and second units are only partly bridged by the connecting elements. The shapes of the cells of the first and second units are axisymmetrical about the connecting element. The curvature radius of the top of the arc constituting the arc part is 1.1 and 1.5 times larger than that of each of the tangent circles formed at the edges of two linear parts of the cell on the circular arc part side.
