Crimp terminal, connection structural body and method for producing the same

A connection structural body, comprising:

• a crimp terminal that is formed of an aluminum substrate of an aluminum material and includes a connection section and a pressure-bonding section including a wire barrel section and an insulating barrel section, the connection section, the wire barrel section and the insulating barrel section being located in this order;
• and
• an insulated wire having an aluminum conductor tip part which is obtained as a result of stripping a front part of a conductive cover for covering an aluminum conductor to expose a front part of the aluminum conductor;
• wherein
• a plated part formed of a plating material containing a nobler metal material than the aluminum material is provided on a contact part of a surface of the aluminum substrate where the aluminum substrate contacts another conductive member,
• an insulating body is formed on a border between the aluminum substrate and the plated part along an outer periphery of the plated part,
• the insulating body is formed of an insulating resin cover which is formed of an insulating resin,
• the insulating resin cover is formed on an area of the aluminum substrate that is exposed outside the outer periphery of the plated part,
• the insulating resin cover includes
• an aluminum substrate insulating resin cover located on the surface of the aluminum substrate, and
• a plated part insulating resin cover located on a surface of the plated part,
• the aluminum substrate insulating resin cover and the plated part insulating resin cover are formed integrally as striding over the border between the aluminum substrate and the plated part along the outer periphery of the plated part, and
• the aluminum conductor tip part is connected to the wire barrel section by pressure bonding.
