High energy behavior of the electromagnetic cascade shower has been studied. The high energy cascade showers were created by electron beams with energies of 25, 50, 75 and 100 GeV at Fermilab. The cascade showers were observed by a detector consisting of multi-layer lead plates and proportional chambers. The experimental results were analyzed with special emphasis on the fluctuation problem of the electromagnetic cascade shower. The formulation on the longitudinal cascade shower fluctuation is made in terms of the correlation matrix. Furthermore, the correlation matrix for the shower fluctuation is generalized to a continuous correlation function.
