An electronic device with fingerprint sensing function including a display panel, a fingerprint sensing module and a supporting frame are provided. The fingerprint sensing module includes a light source and an image sensor. The light source is configured to emit an illuminating light. The supporting frame is disposed between the display panel and the fingerprint sensing module for supporting the display panel. The supporting frame includes a first plane facing the display panel, a second plane facing the fingerprint sensing module, and an oblique through hole between the first plane and the second plane. The illuminating light is guided toward a sensing object above the display panel through the oblique through hole.
