A light-guiding structure including a plurality of light pipes, a plurality of connecting portions and a fixing socket is provided. The light pipes are disposed on the fixing socket, and the light pipes are connected together by the connecting portions. At least one to-be-destroyed portion is formed between the connecting portions. In addition, the fixing socket has at least one destructive structure for disconnecting the connecting portions from each other by destroying the to-be-destroyed portion. Therefore, the interference caused by the light wave passing through the connecting piece is avoided.
