A wiring substrate includes a core layer, first and second wiring layers, and a first insulating layer. The core layer has one and another surfaces and includes a plate-shaped member formed of an aluminum oxide and multiple linear conductors penetrating the plate-shaped member in a thickness direction of the plate-shaped member. The first wiring layer is formed on the one surface of the core layer. The second wiring layer is formed on the other surface of the core layer. The first insulating layer has a same thickness as the first wiring layer and is formed in an area of the one surface of the core layer on which the first wiring layer is not formed. The first and second wiring layers are positioned superposing each other in a plan view. The first and second wiring layers are electrically connected by way of the multiple linear conductors.
