PROBLEM TO BE SOLVED: To provide a water cutoff construction method for concrete connection objects and a water cutoff connecting member, which connects connection objects such as civil engineering materials or building materials together simply and reliably via the accurate fitting positioning of a connecting member main body of an elastic material, is excellent in a rigid connecting property, a following-up property to external force such as an earthquake, and a water cutoff property, is easy to manufacture and design, and can reduce the manufacturing cost. SOLUTION: Arrow-shaped lock sections 6a locked in fitting holes 3 provided at the depths from opening sections 4 facing the connecting faces 2 of concrete connection objects A, B are provided at least at one side end of a connecting member main body 6 made of an elastic material. Cleavage space sections 9 are formed in the thickness direction nearly crossing the longitudinal direction I in the connecting member main body 6.
