Claims

[Scope of utility model registration request]

(1) 1 having a conductor and a contact fixed to the conductor
For at least one contact in a pair, the tip end surface of the contact and the tip end surface of the conductor are flush with each other, and
A circuit breaker in which the width of the contact is set to be the same as or larger than the width of the conductor.

(2) The circuit breaker according to claim 1, wherein a pressure reflector made of a high-resistance material having a higher resistivity than the conductor is provided on the conductor except for the tip end surface of the conductor. −
