Abstract
In the elastomer porous material of the invention, when cells in a first observation region of a first cross section are observed at a certain magnification, cells having a shape factor SF, which indicates the remoteness from complete roundness and is represented by the following formula: (wherein A represents the area of each cell, and P represents the perimeter length thereof), of 130 or less account for 80% or more of all cells in the first observation region, and, when cells in a second observation region of a second cross section orthogonal to the first cross section are observed at a certain magnification, cells having a shape factor SF, which indicates the remoteness from complete roundness and is represented by the same formula (wherein A represents the area of each cell, and P represents the perimeter length thereof), of 130 or less account for 80% or more of all cells in the second observation region.
