PURPOSE: To suppress shock vibrations at the time of sliding and to realize comfortable riding feeling by composing a fiber reinforced composite material constituting a ski plate of an inorganic fiber containing polyvinyl alcohol fiber reinforced composite material.

CONSTITUTION: In a ski plate employing a fiber reinforced composite material in a part of the composing member, a portion or the whole of the fiber reinforced composite martial is composed of a fiber reinforced composite material having reinforcing materials 6, 7 made of an inorganic fiber (for example, glass fiber, carbon fiber) containing polyvinyl alcohol fiber. Said polyvinyl alcohol fiber is adapted to have at least 15g/d of tensile strength and at least 200g/d of tensile modulus of elasticity. Thus, shock vibrations can remarkably be reduced at the time of sliding resulting in a comfortable riding feeling.
