PROBLEM TO BE SOLVED: To provide a spacer which endures repeated use, is light in weight, and is superior in handleability and cushioning. SOLUTION: The transportation spacer is rectangular in elevation and tabular as a whole, and is made of a polyolefin resin foaming material. The spacer has a thickness of 10 to 200 mm, a density of 10 to 90 g/L, and a bending elastic modulus of 1,000 to 30,000 KPa, and shows a residual deformation of 25% or less after being subjected to compression of 75%.
