To provide a hair iron capable of giving an effective treatment care to hair and minimizing damage on hair with strips of elastic members mounted on hair holder members, and also capable of improving the qualitative nature hair intrinsic to through providing adequate moisture (smoothness sense), slickness, in finger-coming, easiness in hair-setting, and gloss moisture for hair, by making use of the effects of negative ions and electromagnetic waves (micro-energy), derived from multi-element mineral powder.

A pair of arm bodies 1 and 2 is pivoted and openably and closably connected on one end together, with each having hair holder members 10 or 20 including heating means 11 or 21 at the other end. As the arm bodies open or close, the hair holder members get apart from or get closer to each other. Strips of the elastic members 15 and 25 are mounted on the hair holder members, extending in the longitudinal direction of the arm bodies in a state of its upper surface protruding from hair holder surfaces 16 and 26, wherein the elastic member contains multi-element mineral powder obtained pulverized multi-element minerals.
