Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heating connection device and a heating connection method, which are capable of preventing a flexible board from separating from a hard board after they are connected to each other by improving bonding strength in joints when soldering and thermocompression bonding are carried out at the same time. SOLUTION: A heater chip 201 is equipped with a first heating unit 202 which heats a first joint formed by soldering a terminal unit 3 formed on the hard board 1 to a terminal unit formed on the flexible board 4 and a second heating unit 203 which heats a second joint adjacent to the first joint and formed by the use of a thermal adhesive tape 8 bonding the hard board 1 to the flexible board 4. A level difference 11 between pressing surface of the heating units 202 and 203 is so set as to make an adhesive agent layer formed on the thermal adhesive tape 8 thick enough to enable the adhesive agent layer to attain prescribed bonding strength when the second joint is pressed.
