摘要： A fiber reinforced plastic spring is provided, in which broken pieces can be prevented from being scattered when breaking without using any additional member and variation in load when breaking can be reduced. FRP spring 1 has a layered structure 20 having basic unit 20A consisting of positive direction orientating layer 21 and negative direction orientating layer 22. Orientating directions S1 and S2 of the positive direction orientating layer 21 and the negative direction orientating layer 22 mutually adjacent are mutually intersecting. By appropriately setting an absolute value of orientating angles ¸1 and ¸2 of each layer 21 and 22, fibers in the positive direction orientating layer 21 and the negative direction orientating layer 22 can be entangled mutually, and thus, the spring as a whole exhibits pseudo-ductility in a breakage condition. Elastic modulus and strength available for use as a spring can be obtained and breaking at a resin portion between fibers can be prevented in each layer 21 and 22.
