A fastening structure includes first and second board-like members to be fastened, a stopping and anchoring part for latching these board-like members to be fastened, and a stopping and anchoring part holding board-like member between the first and second board-like members to be fastened. For a hole of a first inner diameter formed in the first board-like member to be fastened, and a hole of a second inner diameter formed in the second board-like member to be fastened, a smaller hole of a third inner diameter is formed in the stopping and anchoring part holding board-like member, and the impact of gap of the member in production tolerance is avoided thus enhancing the fastening function.
