A HIPE foam may including a vinyl-based crosslinked polymer as a base material resin. The vinyl-based crosslinked polymer may be formed by crosslinking a polymer of a styrene-based monomer and/or an acryl-based monomer. An apparent density ρ of the HIPE foam may be 35 kg/m.sup.3 or more and 500 kg/m.sup.3 or less. A molecular weight between crosslinking points of the vinyl-based crosslinked polymer forming the HIPE foam may be 2×10.sup.3 or more and 2×10.sup.5 or less. The HIPE foam may be used as, for example, a machinable material or an impact absorbing material.
