Abstract: A light guiding apparatus, a light emitting device, an electronic device, and a key are provided. The light guiding apparatus includes a light guiding body, where a prism structure is disposed in the light guiding body, and the prism structure is configured to reflect light that enters the light guiding body; and the light guiding body has a light incident surface and a light emitting surface, where the light incident surface is an irregular surface matched with the prism structure and is configured to reflect light, which is reflected back from the prism structure, to the light emitting surface. The light guiding apparatus provided in the embodiments of the present invention can effectively scatter incident beams emitted by a light source, so that uniform emergent light can be obtained.
