A joint member is provided that can be easily installed, without sacrificing an appearance, in a joint groove required to secure water-tightness between adjoining wall surface facing members of a building. A joint base member 6 is integrally and consecutively installed on a surface of a synthetic resin joiner 4 positioned and provided between wall surface facing members A. The joint base member 6 has right and left side plates 12, two soft sealing tongue flaps 14a and 14b which are protuberantly provided on the outer side surfaces of the side plates and the distal ends of which come in contact with end surfaces of the wall surface facing members, and numerous apertures 16 drilled between the sealing tongue flaps, a sealant 8 being charged in a gap between the side plates. A core member 10 pushed into the gap between the side plates 12 of the joint base member is formed by consecutively installing a core portion 10A for pushing out the sealant 8 through the apertures by being pushed into the gap between the side plates 12, and a jaw plate of a head portion 10B that covers a mouth portion of a joint groove. The core portion 10A has a length that does not cause itself to reach a bottom portion of a sealant charge area S3 between the side plates 12 when the core portion 10A is pushed in.
