Longitudinal Josephson plasma in high-Tc cuprates is formulated by using a intrinsic Josephson coupling model in which the charging effect due to the Cooper pair transfer between the layers is taken into account. The power absorption of microwave due to the longitudinal plasma excitation is calculated. It is verified that the sharp absorption peak observed in the microwave experiments in Bi2Sr2CaCu2O8+δ originates from the excitation of the longitudinal plasma.
