Beschreibung
Zusammenfassung:	Disclosed is a vacuum circuit breaker (1) including a vacuum interrupter (3) accommodated in a ground tank (2) filled with insulating gas. At least one of a fixed electrode (10) and a movable electrode (11) of the vacuum interrupter (3) uses an electrode material in which particles containing a solid solution of a heat resistant element and Cr are finely and uniformly dispersed and in which Cu textures as a high conductive component are finely and uniformly dispersed. The electrode material contains 20 to 70% by weight of Cu, 1.5 to 64% by weight of Cr and 6 to 76% by weight of the heat resistant element relative to a weight of the electrode material. The particles of the solid solution in the electrode material have an average particle size of 20 µm or smaller.
