  We present a new scenario to explain the soft X-ray excess in Active Galactic
Nucleus. The magnetic reconnection could happen in a thin layer on the surface
of accretion disk. Electrons are accelerated by shock wave and turbulence
triggered by magnetic reconnection, then they take place inverse Compton
scattering above accretion disk which contributes soft X-rays. Based on
standard disk model, we estimate the magnetic field strength and the energy
released by magnetic reconnection along accretion disk, and find that the
luminosity caused by magnetic reconnection mainly emits in the inner disk which
is dominated by radiation pressure. We then apply the model to fit the spectra
of AGNs with strong soft X-ray excess.
