Claim 0:
1. A laminated glass set that is a set of a plurality of laminated glasses, wherein:
each of the plurality of laminated glasses comprises a first lamination glass member, a second lamination glass member, and an interlayer film part arranged between the first lamination glass member and the second lamination glass member,
the interlayer film part comprises a first end side, a second end side opposite to the first end side and a colored part, and the interlayer film part in each of the plurality of laminated glasses has an identical composition,
the colored part comprising a gradation part where visible light transmittance increases from the first end side toward the second end side of the interlayer film part, and the gradation part forms a tip of the colored part on the second end side of the interlayer film part, and
wherein:
when a distance X from the first end side of the interlayer film part to the tip of the colored part on the second end side of the interlayer film part is measured in the plurality of laminated glasses, a set of distances X is obtained, a maximum value of the set of distances X is denoted by Xmax, a minimum value of the set of distances X is denoted by Xmin, and an average value of the set of distances X is denoted by Xave, and the laminated glass set satisfies the following formula (1), or
when a distance Y of the colored part in a direction connecting the first end side and the second end side of the interlayer film part is measured in the plurality of laminated glasses, a set of distances Y is obtained, a maximum value of the set of distances Y is denoted by Ymax, a minimum value of the set of distances Y is denoted by Ymin, and an average value of the set of distances Y is denoted by Yave, and the laminated glass set satisfies the following formula (2):

0.005≤(|Xmax−Xmin|)/Xave≤0.1  formula (1)

0.005≤(|Ymax−Ymin|)/Yave≤0.1  formula (2).
