PURPOSE: To obtain a manufacturing method of an electronic component in which the electronic component with a vibration electrode is manufactured with high reliability without rinsing residual flux.

CONSTITUTION: A flux including a nonionic halogen group activator is used for soldering one ends of lead terminals 6a, 6b to lead electrodes 5a, 5b of a ceramic element 2. A wax 9 is dripped to the surrounding of vibration electrodes 4a, 4b after soldering them and an outer package resin 10 is coated and dried around the ceramic element 2 or the like, then air holes are formed in the outer package resin 10. Then the outer package resin 10 is heated to 150°C and then cured. While the temperature rises, the wax 9 and the residual flux 11 are absorbed in the outer package resin 10 and a cavity 8 is formed around the vibration electrodes 4a, 4b. Furthermore, the outer package resin 10 is cured and then an outer package member 7 is formed.
