PROBLEM TO BE SOLVED: To provide a headphone that fits well and is adaptable to a wide range of head size.SOLUTION: In a widened state where both ends of a headband 101 of a headphone 100 are forcibly widened to a width W1 of the 97.5 percentile of the head width in head size data, the headband 101 includes a head top corresponding unit 111 that is curved with a widening radius R1 obtained by adding a value of about 4 mm to a half value of the head length of the 97.5 percentile as a radius of curvature, and a holding portion 112 for holding sound generating means 102. In a free state, the head top corresponding unit 111 is curved a little by its own elastic force, and the holding portion 12 is provided with an adjusting portion 104 that allows the sound generating means 102 to move in the vertical direction.SELECTED DRAWING: Figure 3 【課題】装着感が良く、広い範囲の頭体の大きさに対応できるヘッドフォンの提供。【解決手段】ヘッドフォン１００のヘッドバンド１０１は、頭体寸法データにおける頭幅の９７．５パーセンタイルの幅Ｗ１に両端部を強制的に拡幅した拡幅状態において、９７．５パーセンタイルの頭長の半値に４ｍｍ程度の値を加えた拡幅半径Ｒ１を曲率半径として湾曲する頭頂対応部１１１と、発音手段１０２を保持する保持部１１２とを備え、頭頂対応部１１１は、自由状態において、自らの弾性力により小さく湾曲し、保持部１２は、発音手段１０２を上下方向に移動可能とする調節部１０４を備えるヘッドフォン１００。【選択図】図３
