Provided are a method for producing an electrode material for a vacuum circuit breaker, whereby withstand voltage, high current interruption performance and capacitor switching performance can be improved; an electrode material for a vacuum circuit breaker; and an electrode for a vacuum circuit breaker. A contact material for an electrode for a vacuum circuit breaker has an integral structure consisting of a central member and a CuCr outer peripheral member, the central member having been produced as described above and comprising 30 to 50 wt % of Cu of a particle diameter of 20 to 150 m and 50 to 70 wt % of MoCr of a particle diameter of 1 to 5 m, while the outer peripheral member being formed of a material, which is highly compatible with the central member, shows excellent interruption performance and had high withstand voltage, and being provided outside the central member and fixed thereto.

A vacuum valve according to embodiments of the present disclosure, comprising: an electrode having a first surface which a hollow part is formed on, which electrode spiral electrode slits which slantingly cross an axial direction are formed on outer circumference of, a conductor fixed on a second surface of the electrode, which second surface is opposite side of the first surface, a contact point having a first concavity which opens to the conductor side, which contact point is fixed on the first surface of the electrode, and a connecting plate whose resistivity is lower than one of the contact point, which connecting plate is disposed inside the first concavity, and connecting plate slits which extend inward from circumference as a starting point are formed on, wherein central axes of the connecting plate slits incline in a rotatory direction of the spiral of the electrode slits.
