摘要：

Status report of the JLQCD Collaboration in the lattice QCD calculation of weak matrix elements is made. A precise determination of the kaon B parameter B-K is made with the staggered quark action. B-K is estimated also with the Wilson quark action solving the mixing problem of four-quark operators based on chiral Ward identities. The B meson decay constant f(B) and the B-B parameter are calculated with the propagating Wilson quark.
