A door weather strip includes an attachment base part attached to a door sash part. The attachment base part has at least a part made of a hard rubber. The door weather strip includes a hollow seal part made of a soft rubber. The hollow seal part has a base bottom portion disposed so as to come in contact with the outer surface of a door inner panel, and comes in contact with a body outer panel so as to be deflected and deformed in a door closed state. The door weather strip includes a connection part made of soft rubber connecting the base bottom portion of the hollow seal part with the attachment base part and hard rubber buried inside the base bottom portion and connection part.

A bonding sheet material for a weather strip disclosed herein is a composition including at least EPDM, a cross-linking agent, and carbon black, and has a volume resistivity of 1.010.sup.6 .Math.cm or more based on a double ring electrode method of JIS-K6271-1: 2015 where a test piece has a thickness of 2 mm. When the composition is placed in a mold and molded to press the composition at 50 C. under 100 Kgf/cm.sup.2 for 60 seconds whereby a molded article is produced, the molded article has a thickness change rate of 100% or less, the thickness change rate being represented by formula (1): Thickness change rate=((thickness of molded article after 30 minutes from releasing pressthickness of mold)/thickness of mold)100.
