PROBLEM TO BE SOLVED: To solve the problem that an electric signal having a high frequency cannot be transmitted to a wiring conductor at a high speed. SOLUTION: A semiconductor device is composed of a base body 1 on which a semiconductor element 6 transmitting and receiving the electric signal having the high frequency is loaded, the ground wiring conductors 2b and the first wiring conductors 2a formed to the base body 1, pads 3b for a ground and pads 3a for an input and an output electrically connected to the wiring conductors 2b and the wiring conductors 2a, the second wiring conductor 4 formed to the base body 1, and a connector 5 electrically connected to the wiring conductor 4. The base body 1 is formed of a sintered body in which an Si component is contained in 25 to 80 mass % in terms of SiO<SB>2</SB>, a Ba component in 15 to 70 mass % in terms of BaO, a B component in 1.5 to 5 mass % in terms of B<SB>2</SB>O<SB>3</SB>, an Al component in 1 to 30 mass % in terms of Al<SB>2</SB>O<SB>3</SB>, and a Ca component at a value from O mass % to 30 mass % in terms of CaO.
