In a terminal assembly for electronic and electric equipment, the terminal member is formed into the shape of letter-C by being provided with a middle piece, and first and second arms extending from two opposite ends of the middle piece at an acute angle and at an obtuse angle, respectively. The first and second arms are fitted into a retaining window of a casing to secure the terminal member onto the casing. The first arm is reduced in thickness from its middle part toward its free end or is otherwise increased of its flexibility so as to form a spring portion. A terminal screw is threaded into the middle piece toward the first arm at an oblique angle. A connecting electrode of a circuit board received in the casing resiliently engages the spring portion of the terminal member. Thus, the structure of the terminal assembly is simplified, a favorable resilient contact is ensured between the terminal member and the circuit board, the terminal assembly is made easier to use, the terminal screw can be securely threaded into the middle piece, and the size of the terminal assembly is minimized.
