Abstract: A printing apparatus as an example of an electronic device includes an indicator lamp that emits light in a predetermined color when an abnormality occurs. The indicator lamp includes a light source, and a light reflecting member on which light emitted from the light source is incident and that reflects the incident light. The light reflecting member includes a reflecting surface at which light is reflected. The reflecting surface includes a plurality of individual reflecting surfaces formed in a surface shape of at least a part of a conical surface having an axis forming a predetermined angle with respect to a traveling direction of incident light. The plurality of individual reflecting surfaces are arranged side by side in a first direction intersecting the traveling direction of the incident light.
