Camera module and electronic device comprising same

An electronic device comprising a camera module,

• wherein the camera module includes:
• a lens assembly;
• at least one reflective and refractive member configured to reflect and/or refract light at least twice;
• and
• an image sensor (IS),
• wherein the reflective and refractive member is further configured to totally reflect at least a portion of light incident on the reflective and refractive member by satisfying the following inequation regarding a refractive index for total reflection inside the reflective and refractive member,
