Abstract: An electronic device is provided. The electronic device includes a housing that includes a sensing surface, a light emitting unit that outputs a light through the sensing surface, a light receiving unit that collects a reflection light reflected from an external object in contact with the sensing surface, after the light is output from the light emitting unit, and a first Fresnel lens that is disposed between the light receiving unit and the sensing surface. A first surface of the first Fresnel lens total reflects the reflection light introduced in a direction perpendicular to the sensing surface, and a second surface of the first Fresnel lens refracts the total reflected light so as to be introduced to the light receiving unit.
