Electronic Stethoscope

An electronic stethoscope comprising:

• a casing that has a first end surface that is adapted to face an organism when being used, a second end surface that is situated on a side opposite to the first end surface, and an outer peripheral surface that connects the first end surface to the second end surface;
• a sound sensor that is provided at the casing and that is adapted to obtain the a sound of the organism and to convert the sound of the organism into an electrical signal;
• a light-emitting element that is provided in the casing and that has a light-emitting surface that emits light;
• and
• a light-guiding member that guides the light of the light-emitting element to outside of the casing,
• wherein the light-guiding member has
• an inner surface that includes a light-receiving portion that faces the light-emitting surface of the light-emitting element and upon which the light of the light-emitting element is incident, and
• an outer surface that is exposed to the outside of the casing by extending along the outer peripheral surface of the casing when viewed in a facing direction in which the first end surface and the second end surface face each other, and that radiates to the outside of the casing the light that is incident upon the outer surface through the light-receiving portion.
