The invention provides an intravascular stent applicable to a conical blood vessel. The intravascular stent comprises a plurality of support rings and connecting units, the connecting units are connected between each two adjacent support rings. Each support ring is composed of unit waves identical in shape, and wave height h is gradually reduced from the first support ring at the left end of the intravascular stent to each two adjacent support rings along the axial direction of the intravascular stent. Rib width L is gradually increased from the first support ring at the left end of the intravascular support to each two adjacent support rings along the axial direction of the intravascular stent. Rib width w of the connecting units between each two adjacent support rings is kept constant, and axial length r is equal to the average value of the wave height of the two connected support rings. Instant dumbbell problem is avoided during expanding of the stent, and a gradually thin conical structure after expansion appears, the intravascular stent can well match with human blood vessels, and adherence of the intravascular stent to the human blood vessels is well improved.
