Abstract

A hair iron 1 includes a first arm 21 and a second arm 22 to give a treatment by holding hair between the first arm 21 and the second arm 22. The hair iron 1 includes a first contact part 41 that comes into contact with hair during the treatment, a second contact part 42, and heaters 71 and 72 that heat the first contact part 41 and the second contact part 42, respectively. The first contact part 41 is disposed inside an opening 21a, which is provided in a portion of the first arm 21, the portion facing the second arm 22, while the second contact part 42 is disposed inside an opening 22a, which is provided in a portion of the second arm 22, the portion facing the first arm 21. The first contact part 41 and the second contact part 42 include a substrate 411 and a substrate 421, respectively, each of which is made from isotropic high-density graphite.

Claims

1. A hair iron comprising an elongated first arm and an elongated second arm, wherein one end of the second arm along a longitudinal direction is pivotally attached to one end of the first arm along a longitudinal direction, and another end of the second arm is movable in a direction along which the other end of the second arm comes closer to, or away from, another end of the first arm, and wherein a treatment is given by holding hair between the first arm and the second arm, the hair iron comprising:

a first contact part that is disposed in a portion of the first arm, and comes into contact with hair during the treatment, the portion facing the second arm;

a second contact part that is disposed in a portion of the second arm, and comes into contact with hair during the treatment, the portion facing the first arm; and

a heater that heats at least one of the first contact part and the second contact part,

wherein at least one of the first contact part and the second contact part includes a portion made from a material containing graphite.

2. The hair iron according to claim 1,

wherein the at least one of the first contact part and the second contact part including a portion made from a material containing graphite comprises a DLC film that covers at least part of a surface of the portion.

3. The hair iron according to claim 1, further comprising:

a cooler that cools at least one of the first contact part and the second contact part.

7. The hair iron according to claim 2, further comprising:

a cooler that cools at least one of the first contact part and the second contact part.

4. A hair iron comprising:
