ELECTRICAL CONNECTION BOX

An electrical connection box (10) includes a bus bar (11), a case (15) to which the bus bar (11) is fixed, a terminal (32) that is connected to the bus bar (11), a fixing member (25) that fixes a connection portion (11A) at which the terminal (32) and the bus bar (11) are connected to each other, and a base member (20) that holds the fixing member (25). The fixing member (25) and the base member (20) are disposed at a position at which the fixing member (25) and the base member (20) overlap the connection portion (11A) of the bus bar (11), and when the connection portion (11A) at which the terminal (32) and the bus bar (11) are connected to each other is fixed, the base member (20) moves in a direction in which the base member (20) comes into contact with the bus bar (11).
