Abstract: A drilling jig for drilling a punching hole with a boundary between a basis material and a coating of a workpiece less noticeable, and a drilling method using this drilling jig. It includes a male blade, a female blade, and a hexagon bolt; the male blade and the hexagon bolt are capable of being coupled to each other; a screw hole, through which the hexagon bolt is inserted, and a blade portion are formed in the male blade; the blade portion has a planar blade surface; a shaft insertion hole, through which the hexagon bolt is inserted, and a blade portion housing hole capable of housing the blade portion are formed in the female blade, whereby the boundary between the basis material and the coating of a bumper can be positioned on the inside of the punching hole, preventing the appearance of the punching hole from being impaired.
