Lateral distribution of electrons is determined with scintillators of 50 and 3 mm thickness from the core to 500 m in the Akeno array. Lateral distribution can not be represented by the NKG function with a single age parameter. From size and depth dependence of age parameter and its fluctuation at fixed muon size, elongation rate and fluctuations in the depth of shower maximum are estimated and discussed.
