PROBLEM TO BE SOLVED: To provide a composite conductor wire capable of reducing an eddy current loss and capable of additionally performing connection with an excellent state where reliable conductivity is secured, and further to provide a connection structure, a conductor connection member, a melting connection device and a connection method of the composite conductor wire.SOLUTION: Connection side end portions 16 are heated at a temperature at which high melting point conductors 20 melt while connection side end portions 16 in composite conductor wires 12A are abutting against each other. In the connection side end portions 16, a volume of each high melting point conductor 20 is set to be less than a volume of each low melting point conductor 30. Consequently, the high melting point conductors 20 are caused to sufficiently melt to be in a melting connection state where reliable conductivity is secured while the low melting point conductors 30 are being caused to melt to be in the melting connection state where the reliable conductivity is secured and joint portions 60 can be formed. On this account, a connection structure wire 102 capable of being used for, for example, winding for a motor can be configured.
