In this talk, I plan to review the unparticle idea, briefly.
Then I will talk about the basic points of one of my recent
projects which deals with the effects of the unparticles
on the parity violating asymmetry for the low energy
electron-electron scattering, e-e--->e-e-. I present the limits
on the unparticle coupling lambdaAV, and
on the energy scale Lambda at 95% C.L. for various values
of the scaling dimension d according to the
data from the E158 experiment at SLAC
