A locking structure of a screw-fastening block includes: a screw-fastening block made by providing a screw member for screwing and connecting a bus bar, a terminal, or the like on an upper portion of a screw-fastening block main body; and an electrically connecting block main body having a receiver into which the screw-fastening block is inserted upward side and in which the screw-fastening block is received. Locking portions are provided on both sidewalls of the receiver, and a bottom surface of the screw-fastening block main body is a lock-receiving portion to be engaged with the locking portion. The locking portions are locking arms projected obliquely upward from the both sidewalls, and a tip end of the locking arm is provided with a locking surface for supporting the bottom surface of the screw-fastening block main body, and a projecting piece for supporting a side surface of the screw-fastening block main body.
