Disclosed is a stent for the coil embolization of a cerebral aneurysm. The stent according to one embodiment of the present invention is shaped as a cylinder formed of a mesh-structured metal thin wire to enable a coil to fill the inside of said cerebral aneurysm through the empty space formed at an outer surface of the stent, wherein said cylinder may have a center the maximum diameter of which is larger than the maximum diameter of each of both ends thereof. For example, the stent may have a fusiform shape in which the center protrudes further than the ends thereof. Here, the center in its entirety may protrude further than the ends thereof or only one side of the center may protrude further than the ends thereof. In the latter case, the profile of the stent at the side thereof which does not protrude may be linear in its entirety or curved at the center of the profile.
