A building block includes: a brick, at least one pair of fixation posts, a circuit board and a base. The brick includes at least one pair of studs projected from a top thereof. A stud hole penetrates through each stud. The fixation post includes an insulating piece and a conductive piece. A top of the insulating piece is disposed in the stud hole and the conductive piece is disposed in the insulating piece. The conductive piece has an insertion electrode, a contact electrode and a connection electrode extended from a top, a side and a bottom thereof, respectively. The circuit board and the base are sleeved on the fixation posts. The circuit board includes a positive electrode circuit and a negative electrode circuit respectively contacted with the pair of the fixation posts and a functional unit electrically connected with both electrode circuits. |
