Abstract
A relationship between a thickness of a water film at a location of a maximum pressing pressure and a maximum pressure gradient value is deduced. Each corresponding design factor of a wiper blade is determined based on this relationship, and the wiper blade is manufactured. In this way, at the wiper blade, a thickness of the water film right after wiping falls in an appropriate range.
