Disclosed are an elapsed-time indicator and a method for manufacturing same. The method, according to the present invention, comprises: laminating sequentially from the lower part, a base, a background film in color, such as red, and fine-pored film, wherein each of the base, background film and fine-pored film is prepared as a single sheet; forming a plurality of sectional parts by dividing the top portion of the laminated sheet into a plurality of sections; sequentially positioning, in each of the sectional parts, a print layer with a predetermined pattern or design, and development material; preparing upper parts, corresponding to the respective sectional parts, wherein each of the upper parts consists of a single sheet of transparent film, which comprises a forming part having an air layer in the interior thereof, and which forms a boundary part between the forming parts; aligning the boundary parts and the peripheral parts of the upper parts, and hot-pressure welding the aligned peripheral parts of the upper parts with the peripheral parts of the base, lower part film, background film and the fine-pored film; and then, cutting sectional parts with respect to the boundary parts, thereby mass-producing elapsed-time indicators. |
