A shoe sole that is less likely to feel push-up on the sole at the time of landing and suppresses pronation to enable quick weight movement in running or jogging, while being widely available in sports requiring weight movement such as golf, tennis, basketball, soccer, and skateboarding, as well as that is lightweight, has good wearing comfort and provides stable walking even in using on the street or walking. The shoe sole includes a shoe sole main body made of a flexible material, and a plate made of a material having a flexural modulus higher than a flexural modulus of the flexible material constituting the shoe sole main body, in which at least two of the plates are included in the shoe sole main body.

A sheet material for a radio wave absorber and a radio wave absorber formed from the sheet material, where the sheet material is light weighted and has excellent form-retaining capability and workability for field assembling. A sheet material () for a radio wave absorber has a corrugated paperboard structure with an undulated corrugated medium () and a planar liner () that are layered over each other. The corrugated medium () and/or the liner () are constructed from a sheet including an electrical-loss material. A radio wave absorber () is characterized in that the sheet material () for a radio wave absorber is cut, folded, and assembled as a hollow three-dimensional structure body, which has a shape of wedge, polygonal pyramid, or polygonal cylinder.

An electromagnetic wave absorber has a configuration in which at least three hollow tetrahedrons, each having one open face, are connected to one another so that each surface opposite to a respective open face of the hollow tetrahedrons defines a respective side face of a hollow pyramid. Preferably, the electromagnetic wave absorber is made of sheet electromagnetic wave absorption members, which have a corrugated board structure in which at least one sheet includes an electrically conductive material. The electromagnetic wave absorber is low-cost, has reduced transport volume, excellent electromagnetic wave absorption characteristics from low frequency to high frequency with a shorter absorber length, has no or small difference in characteristics due to polarization plane, is lightweight and high in structural strength, and easy to manufacture and install.
