Abstract: Assuming an equation of state as and , an inflationary model of Kaluza-Klein type is studied. By solving the horizon and entropy problems, it is found that the dimension of the extra subspace should be as large as 35 to 70, if the ratio of to Planck length is taken as to . However, the substantial period of the inflation happens at time much larger than the Planck time if we take the ratio as or even a larger number.
