An object of the present invention is to provide a fastening sealing member preventing water leakage reliably, ensuring ventilation properties sufficiently and having excellent fastening strength of siding boards, and a siding boards attachment structure. The fastening sealing member is disposed at the upper, lower, left, and right joint portion of siding boards; and the siding board is fastened to a framework. The fastening sealing member has: abase plate portion having a flat rear side surface; spacing portions formed at both of the left and right ends of the base plate portion; a central horizontally rising plate portion risen from the base plate portion; a central front plate portion formed at the front end of the central horizontally rising plate portion; and supporting portions risen at the left and right sides of the central horizontally rising plate portion. An upper-board engagement portion, a lower-board engagement portion, and a connecting portion are formed at a front end of the supporting portion. The central front plate portion is disposed more backward than the connecting portion. In addition, elastic materials are arranged on top faces of the left and right end portions of the central horizontally rising plate portion.
