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 deg.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. |
