Disclosed are a bifocal lens having two focal distances to enable near image capturing and far image capturing and capable of being manufactured to have a thin profile, and an imaging device including same. A bifocal lens according to disclosed embodiments may include: a refractive optical system having at least one refractive lens element and having a first focal distance; and a reflective optical system having multiple reflective surfaces and having a second focal distance that is different from the first focal distance. Because the refractive optical system and the reflective optical system have mutually different focal distances, the bifocal lens according to an embodiment may be capable of both near image capturing and far image capturing.
