PROBLEM TO BE SOLVED: To facilitate dimensional control and connecting operation. SOLUTION: This circuit breaker 30 has a first coupling element 31 and a second coupling elements 32, which are forcibly decoupled from each other by the explosive force of explosive produced by a squib 36, etc., for breaking a circuit. The first coupling element 31 is provided with a cylinder part 38, and the squib 36 is provided in the depth of the cylinder part 38. An internal thread 40 is provided on the inner peripheral surface of the cylinder part 38. The second coupling element 32 is shaped capable of infiltrating the cylinder part 38, and an external thread 50 that can engage with the internal thread 40 is provided on the outer peripheral surface thereof. |
