Provided is a spinal implant which includes a compact housing usable in common regardless of a bone screw diameter and is good at assembling properties. A spinal implant includes a screw head holding member, a housing, and an insert. The screw head holding member includes a cylindrical section which is elastically deformable in the radial direction and which includes a support section that supports a screw head from a lower side. The housing accommodates the screw head holding member holding the screw head. The screw head holding member further includes an elastic deformable section which is elastically deformable in the radial direction of the cylindrical section so that an engagement section can engage with the inner circumferential surface of the housing.
