An earphone jack is provided to manufacture a ring, a sleeve terminal and an elastic member in an integrated sleeve by drawing processing, thereby significantly reducing the number of components and the number of processing and assemblers, and accordingly lowering manufacturing costs. An earphone jack comprises the followings: a cylindrical insulated housing(10); a tip terminal(30) which is installed within the housing(10), and is connected to a front end socket of a plug; ring terminals(40,50) contacted with a middle socket of the plug; and an integrated sleeve(60) which has a sleeve part(62) for surrounding the insulated housing(10), an inlet part(64) through which the plug is inserted, and an elastic contact part(66) formed within the inlet part(64) and contacted with the rear socket of the plug.
