Abstract

The electroconductive polyurethane foam according to the present invention is obtained by adding and dispersing, in the composition constituting polyurethane foam, a substance with electron conduction mechanism, and a substance with ionic conduction mechanism and mechanically agitating the resultant mixture in the presence of inert gas. The substance with ionic conduction mechanism is an antistatic agent selected from cationic surfactant, anionic surfactant, ampholytic surfactant, and non-ionic surfactant.
