A wiper blade extends in the longitudinal direction and includes blade rubber, a plate spring-like backing, and a rubber holder. The blade rubber wipes a surface to be wiped. The backing imparts rigidity and elasticity to the blade rubber. The rubber holder holds both the longitudinally intermediate section of the blade rubber and the longitudinally intermediate section of the backing. The rubber holder has a backing housing hole for housing and retaining the backing. The backing housing hole longitudinally extends through the rubber holder. A parting line is set at the longitudinal center of the backing housing hole.
