摘要： A vertebral body spacer of the present invention is used by being inserted between a vertebral body and a vertebral body (intervertebral space). The vertebral body spacer has a block body constituted of titanium or a titanium alloy as a main component thereof, and provided with a pair of contact surfaces to be made contact with the vertebral body and the vertebral body. The block body includes needle parts formed into a needle shape having both end portions and a porous part having through holes passing through the porous part in a thickness direction thereof, and a porosity of at least a surface of the porous part is larger than a porosity of each of the needle parts. The needle parts are inserted into the through holes so that the both end portions are projected from the contact surfaces.
