PURPOSE: A spike is provided to reduce manufacturing costs by preventing the bent part of the spike from being easily bent and to securely fix a wood member by forming barbs in the side and bent parts of the spike. CONSTITUTION: A spike comprises a connection part(100) and spike parts(200). The connection part is formed in a plate shape. The spike parts are extended from both ends of the connection part to be vertically bent. Bent parts(210) are formed in the spike parts in a longitudinal direction. Barbs(215) are formed in the spike parts. Hanging grooves are formed in the side edges of the spike parts. Reinforcing grooves are longitudinally formed in the spike parts.
