Provided is a resin substrate for the pillarless windshield which is large yet light-weight and provides excellent visibility, and has further realized a high strength to withstand a load calculated based on air resistance under the driving speed of 150 km/h. The resin substrate for the pillarless windshield has the longest side (SA) fixed to car body (3), wherein the resin substrate is an uneven-thickness structure having viewing section (1) with a mean thickness (d1) of 3-7 mm and thick-walled section (2) with a thickness of 1.3 times the (d1) or more, and satisfies all requirements of following (a)-(d): (a) the resin substrate having thin-walled viewing section (1) in the center, and having thick-walled sections (2B, 2C and 2D) along total three sides of (SB, SC and SD): opposite side (SB) of the longest side (SA), and two sides (SC and SD) between the ends of the longest side (SA) and those of the opposite sides (SB) of the longest side, (b) the viewing section (1) and thick-walled section (2) being made of an optically-transparent thermoplastic resin satisfying 5% or less of a haze at 6-mm thickness measured according to JISK7105, (c) the longest side (SA) having a length (L1) of 900 mm or longer and 2000 mm or shorter, (d) the thick-walled sections (2B, 2C and 2D) having mean thicknesses (d2B, d2C and d2D) each 3.0 times or less of the d1 and an area accounting for 3-20% of the whole area of the resin substrate.
