PURPOSE:To effect a highly reliable sealing, by a method wherein an electronic part having terminal pins is inseted into a thermoplastic resin case molded with a portion of a lid plate connected thereto, and the case supported by a retainer jig so as to project therefrom is pressed against a heated head. CONSTITUTION:A case 5 in the form of a cup with one end open, which has one side of a lid plate 5a connected to a portion of its brim and further has an inductor element 6 housed therein with its exteranal terminal 7 directed upward, is retained in a through hole 3 in a retainer jig 1 disposed on a support table 4. The case 5 is larger in thickness than the jig 1 and is retained with its undersurface slightly extending beyond the undersurface of the jig 1. Then, the lid 5a of the case 5 is closed to cover the bottom surface of the element 6. The depth of a groove 4a in the table 4 has a predetermined dimension. The case 5 is retained while projecting from the undersurface of the jig 1 by a predetermined dimension. The jig 1 retaining the element 6 is mounted on a positioning table 8 of a heating device. The table 8 presses a hot plate 9 of a heated head against the jig 1. Then, a rod 10 is pushed up to weld the lid 5a to the opening edge of the case 5. |
