We discuss the Josephson current for a special weak-link arrangement in superfluid /sup 3/He-B. The weak link is made out of a /sup 3/He-/sup 4/He mixture which separates two regions of pure /sup 3/He. For large separations (D>>xi/sub m/) we find Josephson's current-phase relation J = nv/sub c/ sinphi, and calculate the critical velocity v/sub c/.
