  A new analysis is performed in QCD sum rule for the lightest negative parity
baryon Lambda (1405). Mixings of three-quark and five-quark Fock components are
taken into account. Terms containing up to dimension 12 condensates are
computed in the operator product expansion. It is found that the sum rule gives
much stronger coupling of Lambda* to the five-quark operator so that the
five-quark components occupy about 90% of Lambda (1405).
