PROBLEM TO BE SOLVED: To provide a connection terminal, an aluminum cable having the connection terminal, an ultrasonic welding method, and an ultrasonic connecting apparatus that do not give any excessive ultrasonic application energy and do not give any mechanical damage to a material itself even in the ultrasonic welding between different types of materials. SOLUTION: The aluminum cable 10 has a stranded wire 12 by a plurality of aluminum wires 11. The connection terminal 120 is mainly composed of Cu, and has a connection section 23 connected to a battery or the like, a flat base 21 integrated to the connection section 23, sidewalls 21a formed at both sides of the flat base 21 and the like. An Al layer 24 by Al or an Al alloy is formed on the upper surface of the flat base 21 and on the inner surface of the sidewall 21a by plating or the like. Interfaces of ultrasonic welding become Al of the same kind by the Al layer 24, thus preventing ultrasonic application energy given to the connection section from becoming excessive.
