強固に固定することができる。Therefore, the electrical component 1 for connection has a terminal 13
It becomes possible to obtain high waterproofness between the both end portions 15, that is, the partition portion 11. In the conventional electrical component for connection similar to the electrical component 1 for connection of the present invention except that the through hole 17 is not formed, when air with a pressure of 0.5 kg / cm 2 is fed from the opening 7 side, The air leaked to the opening 9 side after 30 seconds had elapsed. On the other hand, in the electrical component 1 for connection of the present invention, when air having a pressure of 0.5 kg / cm 2 was sent from the opening 7 side, the air leaked to the opening 9 side after 60 seconds to 90 seconds had elapsed. Thus, the electrical component 1 for connection of the present invention was able to obtain higher waterproof performance than the conventional electrical component for connection. Since the resin flows into the through hole 17 of the terminal 13, the terminal 13 can be firmly fixed to the partition 11.
