A wiper blade having a plurality of check holes consecutively formed to pass through portions of a blade in contact with a windshield surface, allows a driver to clearly see a non-wiping portion on the windshield surface as the portions in contact with the windshield surface are worn out and the check holes are open and easily recognize a replacement timing. Mounting a conductive rubber band or a tensile force sensor on the portions of the blade, allows to easily detect a degree of the wear of a blade and, particularly, by changing conductivity or a tensile force as the check holes are open, allows to more easily check the replacement timing. Visually or audibly notifying the driver of the replacement timing according to a detected signal related to the replacement timing, allows the driver to perform safe driving in quick response to the detected signal.
