Attach the filter chip (4) with your hands (2), stick the filter chip (4) on the substrate (3), apply an absorber such as silicone rubber to the end face of the filter chip (4), and then replace the filter chip (4). The electrode and the t-pole of the substrate (3) are connected with silver paste or the like. As shown in FIG. 3, hexaethylene glycol (5) is applied to the surface of the filter chip (4) fixed on the substrate (3). Next, this board (3
) and filter chip (4) are immersed in silicone rubber, and the entire substrate (3) is soaked in silicone rubber (
6) and cure the silicone rubber (6). During the curing process VC of the silicone rubber (6), the hexaethylene glycol (5) on the surface of the filter chip (4) sublimates as shown in Figure 5, and the bond between the filter chip (4) and the silicone rubber (6) sublimates. A space (7) is formed between them, allowing the filter nap (4) to perform its function.Silicone rubber (
After curing of 6), the surface of the silicone rubber (6) is coated with several layers of epoxy resin (8) as shown in FIGS. 6 and 7.

ルタパッケージが侍られる。Effects of the Invention As explained above, according to the method for manufacturing a filter cage according to the present invention, a filter chip on a substrate is coated with hexaethylene glycol, and the filter chip is coated with a silicon comb together with the substrate. After the silicone rubber has hardened, the exterior is finished with epoxy resin, so the hexaethylene glycol sublimes during the hardening of the silicone rubber, ensuring that a space is formed between the filter tip and the silicone comb, which is different from conventional methods. By stacking the filter chips as shown in the figure, the filter chips can function satisfactorily without using a cap, and a filter package that is easy to manufacture, has a small number of parts, and is inexpensive can be used.
