[Problem] The present invention provides an underwater lighting lamp that will not be damaged even if a large fish exerts a large force on the line, and will not be entangled by the line, and can remain on the line even without other components.[Solution] The underwater lighting lamp of the present invention includes: a body (2) formed of a translucent resin material； embedded in the body (2), including light-emitting diodes (3e, 3f) and batteries (3a) Circuit device (3)； a pair of electrodes exposed on the surface of the main body (2) and arranged separately, and the battery (3a) is arranged with water between the pair of electrodes. The current can flow to the pair of electrodes of the circuit device (3) ； Penetrate the first wire hole (6) in the body (2)； and separate from the first wire hole (6) and penetrate the second wire hole (7), the first wire hole (6) and The second thread hole (7) is formed so that each axis crosses at an obtuse angle.[課題] 本發明提供一種水中照明燈，即使大型魚對線施加大的力也不會破損，且不會被線所纏繞，即使不具其他的構件仍可保持在線上。[解決手段] 本發明的水中照明燈，具備：以透光性樹脂材料形成的本體(2)；埋設於本體(2)內，包括發光二極體(3e、3f)及電池(3a)的電路裝置(3)；露出於本體(2)的表面分開配置的一對電極，在上述一對電極間隔著水配設電池(3a)的電流可流動於電路裝置(3)的上述一對電極；貫穿本體(2)內的第1線孔(6)；及與第1線孔(6)分開並貫穿本體(2)內的第2線孔(7)，第1線孔(6)及第2線孔(7)是形成使各個軸線以鈍角交叉。
