PROBLEM TO BE SOLVED: To provide a wiper blade capable of preventing deposition of snow and ice in a cold area, preventing foreign matters such as grit from being caught, and ensuring excellent wipe ability. SOLUTION: The wiper blade 13 comprises a blade rubber 15 having a base part 15a and a wiping part 15b, a backing 16 consisting of a spring attached to the base part 15a, a lever member integrally having a holder part to be connected to a wiper arm and a holding part 14c to hold the base part 15a of the blade rubber 15 at an intermediate portion in the longitudinal direction, and a cover member 17 consisting of an elastic material to cover the base part 15a. The blade rubber 15 has a nerve part 15e to connect the wiping part 15b in a non-tiltable manner to the base part 15a. The wiping part 15b has a reducing part 15f with its width gradually reduced toward the tip side from the nerve part 15e in a sectional shape orthogonal to the longitudinal direction. The contact angle to a wiping surface 50a of the wiping part 15b is set in terms of the deflection of the wiping part 15b itself. COPYRIGHT: (C)2006,JPO&NCIPI
