The utility model discloses an imaging lens module, a camera module and an electronic device. The imaging lens module comprises a lens barrel, a catadioptric lens group, an imaging lens group, a first fixing element and a second fixing element. The lens barrel is provided with a first bearing surface and a second bearing surface which face an object side of the imaging lens module. The catadioptric lens group leans against the first bearing surface of the lens barrel. The imaging lens group is arranged on an image side of the catadioptric lens group and is supported on the second supporting surface of the lens barrel. The first fixing element is used for fixing the catadioptric lens group to the lens barrel. The second fixing element is used for fixing the imaging lens group to the lens barrel. The catadioptric lens group is used for internally reflecting an imaging light of the imaging lens module for at least two times and providing optical refractive power. Therefore, miniaturization is achieved, the light
