Claim 14:
15. The automobile laminated glass according to claim 1,
wherein the automobile laminated glass is curved so as to protrude toward the first glass plate side, and
at least one of Formulas (1) and (2) below is satisfied:

rV×rH≥rMD×rTD  (1)

rV≥0.9990 and rV≥rTD  (2)

where
O denotes a midpoint of an upper side of the second glass plate,
P denotes a midpoint of a lower side of the second glass plate,
Q denotes a midpoint of a left side of the second glass plate,
R denotes a midpoint of a right side of the second glass plate,
LV denotes a length of a curved line OP that extends along a first surface of the second glass plate on an opposite side of the first glass plate,
IV denotes a length of a straight line OP,
Lh denotes a length of a curved line QR extending along the first surface of the second glass plate,
IH denotes a length of a straight line QR,
rV denotes IV/LV,
rH denotes IH/LH,
an MD direction denotes a roll winding direction in which the functional layer is fed out,
a TD direction denotes a direction that is orthogonal to the roll winding direction in which the functional layer is fed out,
rMD denotes a heat shrinkage of the functional layer in the MD direction before and after being heated at 130° C. for 30 minutes,
rTD denote a heat shrinkage of the functional layer in the TD direction before and after being heated at 130° C. for 30 minutes, and
the MD direction of the functional layer coincides with a direction in which the curved line QR extends.
