Fine grooves called "structure" are carved on sliding surface of ski to reduce friction. But it is unknown the cause of it. This study, by designating "structure" as texture, deals with the effect of texture to the coefficient of sliding friction. Accurate measurement of sliding friction is most important element to examine the effect of texture. Generally, the test piece of ski is used to measure the coefficient of friction. It is measured by drawing the test piece or the dummy snow surface. But this method can not say making reproduction of the sliding of using real ski. Then this paper describes with the simple and accurate method. This method uses the accelerometer. Coefficient of friction is calculated by the relation of acceleration and frictional force. Through some examination, it is said that this method is effective and has enough accuracy to detect the change of coefficient by the difference of type of texture.
