An influence of the kinetic and quantum wave properties of the degenerate electron plasma on the P-wave absorption in the metallic films is studied numerically. One has investigated the films having the width of order of the skin depth when the frequencies of radiation are not larger than the plasma frequency. It is found that in case of ordinary electron relaxation time, the power absorptance coefficient of the quantum electron plasma differs from the absorptances of both the classical electron plasma and the classical electron gas. However in case of the large relaxation times, one observes a coincidence of the quantum and the classical absorptances when the frequencies are much smaller than the plasma frequency, and the difference of the absorptances at the frequencies of order of the plasma frequency.
