PROBLEM TO BE SOLVED: To provide a spacer usable even upside down and enabling the avoidance of lowering of the moisture releasing performance of a heat insulation material and the ventilation efficiency of a ventilation passage. SOLUTION: The spacer 1 is formed by providing irregular shapes on a synthetic resin sheet material 1a by vacuum molding. Convex parts 2 having the front surfaces formed in a projected shape and the rear surfaces formed in a recessed shape are formed to project at the large number of portions of the sheet material 1a by bending the sheet material 1a to the surface side. The projected end faces 2a of the convex parts 2 are formed as abutting faces 3 abutting on one of a heat insulating material 16 and an external material 18. The rear face of a flat surface plate part 4 as the remaining portion of the convex parts 2 in the sheet material 1a is formed as an abutting face 5 abutting on one of the heat insulating material 16 and the external material 18. A through hole 6 passed from the front to the rear of the surface plate part 4 is formed therein. Groove parts 7 opening to the projected end faces 2a of the convex parts 2 are formed by recessing them from the projected end faces 2a of the convex parts 2 to the rear face side. Both ends of the groove parts 7 are opened to the side peripheral surfaces 2b of the convex parts 2 rising from the surface plate part 4. COPYRIGHT: (C)2007,JPO&INPIT
