Component-embedded circuit board

Provided is a circuit board with built-in components, which reduces the noise of the circuit board with built-in components on which an electronic component accompanied by a switching operation is mounted. In the component-embedded circuit board, an intermediate conductor is provided between a first conductive layer and a second conductive layer, and a first semiconductor element and a second semiconductor element, which are disposed so as to be separated from each other in the in-plane direction of an insulating layer. The intermediate conductor connects the low-potential-side connection terminal of the first semiconductor element and the high-potential-side connection terminal of the second semiconductor element. A high-potential-side power supply terminal provided in the first conductive layer is connected to a high-potential-side connection terminal of the first semiconductor element through the first conductive layer. A low-potential-side power supply terminal provided in the second conductive layer is c
