A flexible stent comprising: a plurality of circular bodies having a wavy-line pattern and arranged side-by-side in an axial direction of the flexible stent; and a plurality of connection elements that connect the circular bodies that are adjacent and extend around an axis, wherein the wavy-line pattern is formed by connecting a plurality of V-shaped elements in a circular direction of a circular body, each V-shaped element having a substantially V-shape made by coupling two leg portions at an apex, such that adjacent V-shaped elements have apexes facing opposite axial directions, wherein a direction in which one end of a connection element is bent and a direction in which the other end of the connection element is bent are opposite, wherein the one end and the other end of the connection element are connected with portions other than the apexes of the V-shaped elements at the adjacent circular bodies by extending in a direction different from a direction in which each leg portion of the V-shaped elements extends, wherein, when viewing in a radial direction perpendicular to the axial direction, a direction in which an intermediate portion of the connection element extends is inclined with respect to the axial direction, and wherein one of the two leg portions extends along the intermediate portion of the connection element, characterized in that the two leg portions of a V-shaped element consist of a long leg portion and a short leg portion, and the adjacent V-shaped elements in the circular direction of the circular body are connected so that the long leg portion is adjacent to the short leg portion, and the one end and the other end of the connection element are connected respectively to long leg portions of the V-shaped elements of the adjacent circular bodies, and wherein an angle of the long leg portion of the V-shaped element being inclined with respect to the axial direction is 50° to 80°, and an angle of the short leg portion of the V-shaped element being inclined is 5° to 30°. a plurality of circular bodies having a wavy-line pattern and arranged side-by-side in an axial direction of the flexible stent; and a plurality of connection elements that connect the circular bodies that are adjacent and extend around an axis, wherein the wavy-line pattern is formed by connecting a plurality of V-shaped elements in a circular direction of a circular body, each V-shaped element having a substantially V-shape made by coupling two leg portions at an apex, such that adjacent V-shaped elements have apexes facing opposite axial directions, wherein a direction in which one end of a connection element is bent and a direction in which the other end of the connection element is bent are opposite, wherein the one end and the other end of the connection element are connected with portions other than the apexes of the V-shaped elements at the adjacent circular bodies by extending in a direction different from a direction in which each leg portion of the V-shaped elements extends, wherein, when viewing in a radial direction perpendicular to the axial direction, a direction in which an intermediate portion of the connection element extends is inclined with respect to the axial direction, and wherein one of the two leg portions extends along the intermediate portion of the connection element, characterized in that the two leg portions of a V-shaped element consist of a long leg portion and a short leg portion, and the adjacent V-shaped elements in the circular direction of the circular body are connected so that the long leg portion is adjacent to the short leg portion, and the one end and the other end of the connection element are connected respectively to long leg portions of the V-shaped elements of the adjacent circular bodies, and wherein an angle of the long leg portion of the V-shaped element being inclined with respect to the axial direction is 50° to 80°, and an angle of the short leg portion of the V-shaped element being inclined is 5° to 30°.
