A systematic analysis of {alpha}({sup 4}He)-nucleus elastic scattering is made by using a microscopic optical model potential obtained by the double folding of the complex nucleon-nucleon (NN) effective interaction based on the G-matrix theory. We adopt the so-called JLM interaction as the complex NN interaction and test its applicability to the {sup 4}He elastic scattering by {sup 12}C, {sup 16}O, {sup 28}Si, and {sup 40}Ca over a wide range of incident energy and scattering angle. The experimental cross sections for incident energies ranging from E{sub lab}=40 to 240 MeV are well reproduced by the double folding potential up to backward angles. Although modification of the real and imaginary potential strength by about 25% and 35%, respectively, on average is necessary to reproduce the data, the renormalization factors are found to be almost constant with respect to the incident energy and target mass number.
