PROBLEM TO BE SOLVED: To provide a simple and inexpensive connection method of printed wiring boards. SOLUTION: The connection method of the printed wiring boards is provided with (a) a process for supplying uncured non-conductive adhesive to regions which contain bonding parts and are previously decided; (b) a process for supplying gold micro balls 14 to the bonding parts through uncured non-conductive adhesive; (c) a process for making a rigid printed wiring board 11 and the flexible printed wiring board 15 confront each other by positioning the bonding parts and sandwiching them, (d) a process for applying previously decided load to the regions while the previously decided regions containing the bonding parts are kept to a previously decided temperature, applying supersonic vibration which is previously decided, and performing intermetal bonding on the bonding parts through the gold micro balls; and (e) a process for heating the region to the previously decided temperature and completely curing adhesive without giving mechanical load to the regions.
