PROBLEM TO BE SOLVED: To provide a headphone (50) having a lock structure capable of allowing locked codes not to easily come off. SOLUTION: The headphone includes: speaker parts (1L, 1R); the codes (2L, 2R) connected to the speaker parts; and a housing part (4) having a body part (4h) integrally formed with the codes and a pair of arm parts (15b, 16b) to be projected from the surface (4d) of the body part. The pair of arm parts respectively include: base parts (15k, 16k) connected to the surface; middle parts (15tk, 16tk) extending from the base parts and separated from the surface; and distal end parts (15st, 16st) forming slits (15c, 16c) at positions closer to the surface than to the middle parts (15tk, 16tk). The pair of arm parts are formed so as to allow the positioning directions of the slits to be mutually opposite with respect to the respective base parts. COPYRIGHT: (C)2009,JPO&INPIT
