PROBLEM TO BE SOLVED: To provide a crosslinked polyethylene foam containing tourmaline ore which generates a great deal of minus ion without generating a sulfur odor, and its manufacturing method. SOLUTION: A foaming resin compound prepared by adding the tourmaline ore of 0.1μ-0.1μm particle diameter of 5-50 pts.wt., a foaming agent of 2-20 pts.wt. and a crosslinking agent to a polyethylene resin of 100 pts.wt. is heated and foamed, then the crosslinked polyethylene foam containing the tourmaline ore is produced. |
