A luminous press key module, comprising:
- a key cap;
- a base plate disposed under said key cap and formed with a base plate opening;
- a circuit unit disposed between said base plate and said key cap, and having at least a light-transmission region that corresponds to said base plate opening and that is made of a light-permeable material;
- a restoring unit disposed between said key cap and an upper surface of said circuit unit and abutting against said key cap so as to provide a restoring force for biasing said key cap away from said circuit unit;
- and
- a luminous unit including a luminous element that is electrically connected to said circuit unit, that is disposed on a lower surface of said circuit unit opposite to said upper surface of said circuit unit, and that is accommodated in said base plate opening, said luminous element emitting light to said light transmission region for illuminating said key cap.
