This invention provides a terminal block capable of effectively preventing a screw in a clamping portion from being loosened. It has a block body (4), and a clamping member (10) adapted to clamp an object so as to be pressed against a clamping surface (4c) at an inner lower portion of the block body (4). The block body (4) is formed by bending an elongated metal plate at four portions thereof at right angles in the same direction and superposing one of a first and final flaps (4a, 4b) on the other, these flaps (4a, 4b) being provided with circular threaded bores (4a', 4b') so that the threaded bores can be engaged with a shank (1b) of a screw. The clamping member (10) has a screw (1) provided with the threaded shank (1b) having an elliptic cross section extending at right angles to the axis thereof, and a clamping plate (3) joined to a lower end of the shank (1b) of the screw so that the clamping plate (3) is moved vertically in accordance with an axial movement of the screw (1).
