%X Magnetic reconnection plays a key role in the energy release and transformation in geospace. Though Electrostatic Solitary Wave (ESW) is widely observed in space, direct observation in the vicinity of reconnection site is rare, which makes it ambiguous of the characteristic of ESW associated with reconnection. Here we present a reconnection event for which ESW is ample in the separatrix of the reconnection diffusion region. The characteristic of the ESW associated with reconnection is studied and the effect of ESW on reconnection is discussed. The result shows that, the ESWs observed in the separatrix of reconnection which takes place during a substorm, is more solitary and more nonlinear than that in other regions. The ESW associated with reconnection can propel reconnection process via presenting parallel electric field and accelerate electron.
