The illuminated belt buckle (1) comprises a housing (2), a push-button (3) displaceable in the housing (2), an insertion slot (4), bordered by an edge section (21) of the housing (2) and the push-button (3), for inserting a latch plate lockable in the belt buckle (1), at least one light source (10) and at least one light guide (11), wherein the light guide (11) is coupled to at least one light-emitting surface (12, 13) starting from a light entry surface (22). It is provided that a shielding element (14) is arranged on the light guide (11) and shields the light guide (11) at least from a housing part (7, 8, 9) of the housing (2) and/or a cavity (15) in the interior of the housing (2) in which the push-button (3) is arranged. The invention also relates to a method for producing such an illuminated belt buckle (1).
