Abstract
PURPOSE:To form a thin lightweight marking body, by sealing a searching signal responding means between two films or sheets. CONSTITUTION:The coil 1, quartz vibrator 2 and capacitor 3 constituting a searching signal responding means are mutually connected in parallel to be sealed in a state held between two films 4, 5. As each of the films 4, 5, a plastic film bondable by thermal welding or an adhesive is used. At least one of them, for example, the lower film 4 is formed from a plastic film having elasticity and relatively high stiffness and the shape of a marking body is held to a card shape. As the other film 5, a plastic film having extensibility is used so as to be made deformable to follow the outer shapes of the coil 1, quartz vibrator 2 and capacitor 3 when the searching signal responding means is thermally welded or bonded by an adhesive.
