ｐ損失係数ηを算出した。Examples of the present invention will be described below. In this example, the loss coefficient η, which is a measure of vibration damping performance, was calculated as follows using the measuring device shown in FIG. That is, a vibration damping layer is formed by applying various damping paints on the upper surface of an iron support plate 11 and comprising two sheet 1-shaped coating films 12 (first layer) and 13 (second layer) having a predetermined thickness. The supporting plate 11 and one end of the damping laminate are supported on a strong surface plate. Next, after making both of them resonate at their natural frequency using the vibrator 21, the excitation force is instantly reduced to zero and the Hakusan J is made to vibrate, and the reduction of this free vibration is detected by the pickup 22, the amplifier 23, and the real-time analysis. The attenuation degree D (db/s) is determined by measuring using the detector 24 and the level coder 25. From this degree of attenuation, the loss coefficient η was calculated using the following formula.
