We　present　an　economical　scheme　of　five-party　quantum　state　sharing　(FQSTS)　of　an　arbitrary　m-atom　with　five-atom　cluster　state　in　cavity　QED.　It　is　found　that　the　five-partite　cluster　state　can　be　used　for　FQSTS　of　an　arbitrary　m-atom　state.　The　implementation　of　this　scheme　does　not　involve　Bell-basis　or　GHZ-basis　measurements,　which　makes　it　more　convenient　in　a　practical　application　than　some　previous　schemes.　The　scheme　is　also　insensitive　to　the　cavity　decay　and　the　thermal　field.
