PROBLEM TO BE SOLVED: To provide a heat insulation sheet by which a heat insulation effect is favorably achieved even if a window glass is cooled when the heat insulation sheet is attached to the window glass.SOLUTION: A heat insulation sheet 11 is mainly comprised of a first sheet 13, a second sheet 23, and a projection 30. One of outer edges of the first sheet 13 and one of outer edges of the second sheet 23 are joined together, and thus the projection 30 is formed. When using the heat insulation sheet 11, an upper end 37 and a lower end 38 of the heat insulation sheet 11 are attached to an upper end 42 and a lower end 43 of a window glass 41, respectively, by double-faced tapes. Thereby, cool air is prevented from being directly transferred to the heat insulation sheet 11 through the window glass 41 because a space 45 and a space 46 are formed around the projection 30. |
