  We study entanglement witness and present a construction of entanglement
witnesses in terms of the symmetric informationally complete measurements
(SIC-POVM). The capability of our witness is shown by some examples and it can
be found this witness detects more entanglement than previous separability
method given also by SIC-POVM. What's more, comparing with the dimension
dependence of SIC-POVM, we also give the entanglement witnesses can be always
constructed from general symmetric informationally complete measurements
(GSIC-POVM).
