Imaging lens and imaging apparatus

An imaging lens consisting of, in order from an object side to an image side, a front group including one or more lenses, a stop, and a rear group including a plurality of lenses,

• wherein the rear group includes at least one first aspherical lens that has a concave surface facing the image side in a paraxial region and that has, on a lens surface on the image side, an inflection point at which a convex or concave shape changes, and
• in a case where a back focus of the imaging lens as an air conversion distance in a state where an infinite distance object is in focus is denoted by Bf,
• a focal length of the imaging lens in the state where the infinite distance object is in focus is denoted by f, and
• a maximum half angle of view in the state where the infinite distance object is in focus is denoted by ωm,
