<p>A soft contact lens of a novel structure which can attain positional stability of the contact lens by limiting the movement of the lens to within an appropriate range when it is worn without sacrifice in excellent feeling of wearing of a contact lens having an aspherical inner surface profile close to the profile of cornea. Outer circumferential end face (34) of the lens has a cross-section of curved surface projecting toward the outer circumferential side, and the joint (38) of the outer circumferential end face (34) of the lens with the inner surface (26) at the peripheral portion (20) is a corner portion having a cross-section profile of obtuse angle: a and spaced apart radially inward by a distance: x from the outermost circumferential end of the lens, where 0<x=0.1 mm and 120°=a=150°.</p>
