This connecting terminal (10) is provided with a tab and four or more clamping plates (12) that hold an aluminum electrical wire. Each clamping plate (12) has a first slit (13) and contact surfaces (14). Each first slit (13) has a first open end on one side and a first tip on the other side. The aluminum electrical wire is pressed-fitted into the first slits (13). The contact surfaces (14) contact the aluminum electrical wire press-fitted into the first slits (13). The contact area between the contact surfaces (14) and a core wire is between 100% and 200%, inclusive, of the radial cross-sectional area of said core wire.
