We study theoretically the anomalous Hall effect due to vector spin chirality carried by local spins in the s\text\ensuremath-d model. We show that the vector spin chirality indeed induces the local Hall effect in the presence of electron-spin polarization, while the global Hall effect vanishes if electron transport is homogeneous. This anomalous Hall effect can be interpreted in terms of the rotational component of the spin current associated with the vector chirality.
