In a wristwatch case, a nonmetal dial plate ( 305 ) is disposed so as to face a transparent window plate ( 304 ), and a movement ( 303 ) with a built-in antenna is disposed between the nonmetal dial plate ( 305 ) and a nonmetal back cover plate ( 306 ). A metal annular window frame ( 301 ) and/or a metal annular back cover frame ( 302 ) has an extension (L 1 , L 2 ) extending appropriately toward a metal annular base ( 300 ). Thereby, in the wristwatch case, the outer periphery of the movement ( 303 ) with a built-in antenna disposed between the nonmetal dial plate ( 305 ) and the nonmetal back cover plate ( 306 ) is surrounded so that the region is divided vertically, by the metal annular base ( 300 ) and the extension (L 1 ) of the metal annular window frame ( 301 ) and/or the extension (L 2 ) of the metal annular back cover frame ( 302 ). |
