A door weather strip 5 includes an attaching base part 11 that is to be attached along an outer periphery of a door frame 7 and an optional hollow seal part 12a that is extended in an outer peripheral direction of a door from the attaching base part 11. The attaching base part 11 may include a base bottom part 13. Both the attaching base part 11 and the seal part 12 are made of the same EPDM sponge rubber material by an extrusion process. The door weather strip 5 satisfies conditions that a specific gravity is 0. 36 or higher and 0. 44 or lower, a low stretch stress is 200 kPa or higher and 230 kPa or lower and an average foaming cell diameter is 180 pm or larger and 220 pm or smaller. Optionally the surface roughness RzD is 20 μm to 37 pm. |
