SOLUTION: This vehicular door sash is composed of a roof-side sash member (horizontal sash member) 1 which is formed so as to meet a roof panel door opening surface and is provided so as to extend in the horizontal direction; and a longitudinal sash member 2 which is formed so as to meet a B pillar. The roof-side sash member 1 is formed out of a plastic material, using an extrusion molding method based on a die material 11 having a certain cross-section shape, and protrusion portions 12 and 13 are provided at both edges of such sash member 11. Then, the door sash for the vehicle is formed by engaging the protrusion portions 12 and 13 with engaging holes 21 and 31 which are provided on the longitudinal sash member 2 or the door panel 3.
