In order to treat tensor force explicitly, we propose a microscopic model for nuclear structure based on antisymmetrized molecular dynamics (AMD). As a result of the present study, it is found that some extentions of the AMD method are effective to incorporate the tensor correlation into wave functions. Calculating the deuteron, triton and $^4$He with the extended version of AMD, we obtained solutions that have large contribution of the tensor force. By analyzing the wave funtion of $^4$He, it is found that its single-particle orbits are composed of normal-size $0s$ orbits and shrunk $p$ orbits so as to gain the tensor force.
