To provide an indicator lamp capable of improving visibility without increasing the number of light-emitting sources or luminance in the indicator lamp having an annular luminous indication part.SOLUTION: An indicator lamp 37 is an indicator lamp 1 which is mounted on a mounting surface and indicates positions of disaster preventive apparatuses, and comprises a main body part 38 storing therein a substrate 17 on which a light-emitting element 15 is mounted and a luminous indication part 11 through which light emitted by the light-emitting element 15 is permeated. The luminous indication part 11 is ring-shaped, and a transmitter 3 including a push-button 31, a push-button storage part 33 and a transmitter main body 35 is stored at an inner peripheral side of the ring-shaped luminous indication part in a front view. A space part 14 at a back side of the luminous indication part 11 in which the substrate 17 is stored is filled with a semitransparent filler 39 so as to make the space part 14 full, and a reflector 25 is adhered so as to cover a transmitter mounting surface part 21 in a transmitter storage part 13.SELECTED DRAWING: Figure 10 【課題】発光表示部が円環状のものにおいて、発光源の数や輝度を増すことなく視認性を向上させることのできる表示灯を得る。【解決手段】本発明に係る表示灯３７は、取付面に取り付けられて防災機器の位置を表示する表示灯１であって、発光素子１５を搭載した基板１７を収容する本体部３８と、発光素子１５が発光する光を透光させる発光表示部１１とを有し、発光表示部１１は、リング状に形成されると共に、正面視においてリング状の発光表示部の内周側に、押ボタン３１と押ボタン格納部３３と発信機本体部３５を有する発信機３が収容され、かつ、基板１７が収容された発光表示部１１の背面側の空間部１４に、空間部１４を満たすように半透明の充填材３９を充填すると共に発信機収容部１３における発信機取付面部２１を覆うように反射板２５を貼り付けたことを特徴とするものである。【選択図】 図１０
