About 50 years ago, authority of physics academy concluded that Big bang theory is right by the discovery of Cosmic Microwave Background radiation (CMB). But soon, people found serious problem in the Big bang theory so conception called ‘Inflation’ invited, which implies that there was great expansion of space after Big bang between 10-30 s and 10-33 s ~ 10-32 s. At that time, inflaton that caused inflation included asymmetry throughout space. After the inflation, the energy that inflaton had was released as the form of a matter. So, asymmetric inflaton also derived asymmetry of matter. Because of this asymmetry, large scale structure and CMB became to have these days’ shape. In this research, we are going to set simple model of inflaton that contains asymmetry and compare with these day’s CMB by using laplace series. Finally, we could get a result that resemble our universe’s CMB power spectrum.
