PROBLEM TO BE SOLVED: To further reliably fix the spine.SOLUTION: An implant for connecting a vertebra fixing rod is connected to lower ends of first and second spine fixing vertical rods that are inserted into both right/left sides of the spine viewed from the back plane for fixing the spine. The implant for connecting the vertebra fixing rod includes: a horizontal rod for inserting one end into a left-side iliac bone in the horizontal direction and inserting the other end into the right-side iliac bone in the horizontal direction； and first and second connection parts for connecting each of the first and second spine fixing vertical rods to the horizontal rod. The first and second connection parts include tubular members that change the direction so as to match the lateral inclination of the first and second spine fixing vertical rods for inserting the first and second spine fixing vertical rods.
