The wiper blade according to claim 3, wherein: the blade rubber further includes: a wiping lip that wipes the wiping surface; and a connecting body that is connected to the holder and includes the primary grooves; and the fin includes two claws that cooperate together to clamp the connecting body of the blade rubber. 5. The wiper blade according to claim 4, wherein: the connecting body further includes two secondary grooves, which extend in the first direction and are arranged in the first and second lateral sides, respectively, of the blade rubber; and the secondary grooves receive the claws, respectively, of the fin. 6. The wiper blade according to claim 5, wherein: the holder includes at least one pair of claws; and the secondary grooves further receive the claws, respectively, of each pair of the holder. 7. The wiper blade according to claim 6, wherein the blade rubber includes at least one holding portion that engages with the holder to limit movement of the holder in the first direction. 8. The wiper blade according to claim 7, wherein the at least one holding portion of the blade rubber is provided in at least one of the secondary grooves. 9. The wiper blade according to claim 7, wherein the at least one holding portion of the blade rubber holds the holder at a longitudinal center of the blade rubber. 10. The wiper blade according to claim 7, wherein: each holding portion of the blade rubber has a slope; a distance between the holder and a first end of the slope of each holding portion is smaller than a distance between the holder and a second end of the slope of the holding portion; and a distance between a central axis of the blade rubber and the first end of the slope of each holding portion is greater than a distance between the central axis of the blade rubber and the second end of the slope of the holding portion. 11.
