PROBLEM TO BE SOLVED: To provide a cervical spine collar that is better to hold a head, to use, and has better feeling to wear compared to the conventional one.SOLUTION: A cervical spine collar 101 is provided to be used for a cervical spine holding a human head, the cervical spine collar 101 including: a band shaped core material of three-dimensional fiber structure 111 that is made by forming random loops of a fiber material 111a made from a thermoplastic elastic resin and fusing the most part of the contact part of each loop and a surface material 121 for wrapping the core material. Here, the three-dimensional fiber structure has 50% compression hardness of 200 to 1200 N, a fiber diameter of the random loops is 0.3 to 2.0 mm, and apparent density thereof is 0.08 to 0.2 g/cm3.COPYRIGHT: (C)2016,JPO&INPIT【課題】頭部の保持、使用性、装着感が従来に比べて良好である頸椎用カラーを提供する。【解決手段】人の頭部を保持する頸椎に用いる頸椎用カラー101であって、熱可塑性弾性樹脂でなる繊材111aでランダムループを形成し、各ループの接触部の大部分を融着させてなる立体繊維構造体111でなる帯状の芯材と、この芯材を包装する表皮材121とを有し、ここで立体繊維構造体は、その50%圧縮硬さが200から1200Nであり、かつランダムループの繊径が0.3から2.0mmであり、かつその見かけ密度が0.08から0.2g/cm3である。【選択図】図1
