本稿以自由的電話會話來做接續助詞「kedo」用法的調查。LDC的日文語料庫，共計10小時又45分的會話，共有1047個「kedo」來做分析。根據之前的研究，將「kedo」的用法分為六類，並依分類做個別的統計。從結果得知，逆接用法只占全部的12.7 %。而前言、修改、補充說明等等註解的用法占全部的40.7 %。另外終助詞的用法占全部的35.3 %。由這次的研究結果得知，在自由會話中，接續助詞「kedo」的主要用法並非逆接用法而是說明，註解的用法較有可能。從本次的調查結果來看，我認為在日語教學中，教導學生接續助詞「けど」的時候，應該以逆接用法僅僅是「けど」用法中的其中一種而己的觀點來教學，在說明、註解的功能上多加講解，而逆接的用法則不需過於強調。

In this paper private telephone conversations were analyzed. 1047 kedo were used during the conversations of 10 hours 45 minutes in the LDC Corpus. Referred to National Institute for Japanese Language and Linguistics1951 and Morita1989, kedo were categorized into 6 usages and each usage of the data was counted. As a result the data show that contradictory usage accounts for only 12.7 percent. On the other hand kedo with the explanatory meanings such as introductory usage, revised usage, additional explanatory usage accounts for 40.7 percent in total. Modality usage accounts for 35.3 percent. Based on these results, it is considered that the key meaning of kedo is not a contradictory usage but an explanatory one.
