摘要

Connection terminal (10) according to the present invention includes a tab part and not smaller than four pinching plates (12) that hold an aluminum electric wire. Pinching plates (12) each include first slit (13) and contact surfaces (14). First slit (13) has a first open end located in one side of the slit, and a first tip located in the other side. The aluminum electric wire is inserted into first slit (13). Contact surfaces (14) are in contact with the aluminum electric wire that is press-fitted into first slit (13). A contact area in which contact surfaces (14) are in contact with a core wire is an area of 100% to 200% of a radial cross-sectional area of the core wire.
