The connector portions 18 and 20 are for connecting a female connector as an electrical component, the connector portion 22 is for connecting a relay as an electrical component, and the connector portion 24 is for connecting a fuse as an electrical component. It is for doing. In this embodiment, the two connector parts 1
The flange portions 19 and 21 of 4, 15 have the same predetermined external shape and the same external dimensions. Similarly,
The flange portions 23, 25 of both connector parts 15, 16 have the same predetermined outer shape and the same outer dimensions. Note that the outer shapes and outer dimensions of the flanges 19 and 21 are different from the outer shapes and outer dimensions of the flanges 23 and 25. To form the upper case 13 configured as described above, a connector component having a connector to be formed is set at a predetermined position with respect to a mold for manufacturing the upper case 13. Then, a molten synthetic resin as a molten material is injected into the mold. When the synthetic resin injected into the mold is solidified and the mold is removed, the upper case 13 shown in FIGS. 1 and 2 can be obtained.
