May be good.

The first holding portion 42 and the second holding portion 52 may be integrally formed in the case 11.
-In the above embodiment, the first terminal cover 12 and the second terminal cover 13 each hold one terminal, but in addition to this, for example, at least one of the first terminal cover 12 and the second terminal cover 13. However, it may be configured to hold a plurality of terminals.

The number of terminal covers included in the electrical connection box 10 is not limited to the two of the above embodiments, and may be configured to include three or more terminal covers.
The technical idea that can be grasped from the above-described embodiment and modified example will be described.

(A) The case has a first locking portion that locks to the first terminal cover and a second locking portion that locks to the second terminal cover.
The first terminal cover and the second terminal cover are assembled to the case in the same direction as each other.
The first locking portion and the second locking portion are located between the first holding portion and the second holding portion when viewed from the assembling direction of the first terminal cover and the second terminal cover. is doing.

According to this configuration, the first locking portion and the second locking portion are located between the first holding portion and the second holding portion when viewed from the assembling direction of the first terminal cover and the second terminal cover. .. Therefore, the dead space that may occur between the first holding portion and the second holding portion can be more effectively utilized.
