Difficulty of manufacturing is reduced while providing waterproof property with respect to a contact portion with an aluminum core wire. A barrel portion of a crimp terminal includes an inner barrel piece and an outer barrel piece, and an inner surface is provided with a plurality of recesses arranged dispersedly, and a groove extending in in a first region at the outer barrel piece, a second region at a location close to a terminal portion and a third region on an opposite side. A second portion of a seal member formed from adhesive gel is formed into a strip-like shape having width that allows a part thereof to be pushed out after crimping, and a first seal portion is formed into a shape corresponding to the groove and having narrower width than the second seal portion.
