The TeV-X ray flare observed in May of 1994 in the BL Lac object Mrk 421 is interpreted in terms of synchrotron-self Compton (SSC) mechanism. It is suggested that the TeV-X ray flare is produced by a high-energy component of flat electron-energy distribution with a spectral index of αe ≍ 0.25 at low energies. This flaring component is independent of the low-energy component. In addition to the fact that most radio outbursts show flat electron-energy distributions with spectral index αe ≍ 0.2 - 0.4, the result implies that the basic mechanism of particle acceleration in AGNs produces flat energy distributions.
