Window weather stripping for sealing a gap between a movable glass and a window frame having less frictional sliding resistance and longer life time at a lower manufacturing cost. The window weather stripping according present invention comprises at least one microscopically rough surface on which the window glass slides, the rough surface being formed by first painting a bonding agent onto a surface and next spraying particles onto the painted bond or by simply applying a bonding agent mixed with particles. The diameter of the particles is from 5 to 500 micron and the hardness of the particles is from 2 to 7 on the Mohs scale. Talc, nylon, silica, graphite molybdenum, etc. are used as the particles.
