PROBLEM TO BE SOLVED: To provide a conductive connection material capable of reducing variation in thickness of a solder member by reducing temperature differences in an electrode for connection, and to provide a manufacturing method of a module using the same. SOLUTION: The conductive connecting material made of the annular solder member has a cut 3 made in its outer peripheral portion. Through the cut 3, a range from the conductive connection material 10 to the conductor for connection of a substrate as an object of connection by the solder member 1 can be irradiated with laser light so that a range of the conductor for connection which is close to the center of the conductive connecting material 10 can be heated efficiently, and the temperature differences in a formation region of the electrode for connection are reduced to reduce variance in thickness of the solder member 1, after soldering.
