PROBLEM TO BE SOLVED: To provide an earphone which is neither loosened nor dropped during wearing. SOLUTION: An earphone is constituted of a housing 2 and an auricle supporting member 1. The housing 2 incorporates a speaker unit 6 and is held between the side of tragus 12 and the side of ear concha 16 when inserted to the side of an external auditory canal 14 of the concha 13. The auricle supporting member 1 is mounted at the side of the housing 2 for preventing dropping from the side of the ear concha 16. The auricle supporting member 1 is rotated along with a side wall surface 11 partitioning the side of the ear concha 16 and the side of antihelix 15 to be engaged with the side wall surface 11 via a top end part, thereby making dropping difficult during wearing.
