Intermediate film for laminated glass, laminated glass, and method for installing laminated glass

A laminated glass that is a head-up display,

• the laminated glass having a display region of the head-up display,
• the laminated glass comprising a first lamination glass member, a first resin layer, an infrared reflective layer, and a second lamination glass member, the first lamination glass member, the first resin layer, the infrared reflective layer, and the second lamination glass member being arranged side by side in this order, a laminate of the first lamination glass member and the first resin layer being wedge-like, or the laminated glass comprising a first lamination glass member, a first resin layer, an infrared reflective layer, a second resin layer, and a second lamination glass member, the first lamination glass member, the first resin layer, the infrared reflective layer, the second resin layer, and the second lamination glass member being arranged side by side in this order, a laminate of the first lamination glass member and the first resin layer being wedge-like,
• when the laminated glass comprising the first lamination glass member, the first resin layer, the infrared reflective layer, and the second lamination glass member, a laminate of the infrared reflective layer and the second lamination glass member having a thickness of 2.93 mm or less, or a laminate of the infrared reflective layer and the second lamination glass member being wedge-like,
• when the laminated glass comprising the first lamination glass member, the first resin layer, the infrared reflective layer, the second resin layer, and the second lamination glass member, a laminate of the infrared reflective layer, the second resin layer and the second lamination glass member having a thickness of 2.93 mm or less, or a laminate of the infrared reflective layer, the second resin layer and the second lamination glass member being wedge-like.
