PROBLEM TO BE SOLVED: To provide a switch package for switching connection and disconnection between two contacts of an electric circuit, whose signaling course is shortened. SOLUTION: The switch package which is mounted on the two contacts prepared on the surface of a circuit board switches connection and disconnection electrically between the two contacts. The switch package comprises a package laid on the surface of the circuit board; an electrical conductor formed at a position facing the two contacts in the inside of the package; and a drive unit formed in the package for driving the electrical conductor, which switches connection and disconnection between the electrical conductor and the two contacts. Signal wiring connected to the two contacts and a ground layer forming a microstrip line are formed in the circuit board, wherein the electrical conductor may form the ground layer and the microstrip line in a state that the electrical conductor is connected with the two contacts.
