  We study one possible production mechanism for hidden charm pentaquark in
e+e- collision, where it is produced via a color-octet c \bar c pair
fragmentation. The pentaquark production at B factory energy is dominated by
e+e- to c \bar c g to Pc + X. At Z^0 pole, for the pentaquark production, there
are several partonic processes playing significant role. Our results show that
it is possible to search for the direct pentaquark production signal at e+e-
colliders, which is important to understand the properties of pentaquark.
