Abstract: Disclosed is a power module with built-in power device and double-sided heat dissipation and a manufacturing method thereof. The power module includes a first base plate including a first organic insulating base material, a first electrical insulating heat dissipation body, a first metal layer, and a patterned second metal layer; a second base plate including a second organic insulating base material and a second electrical insulating heat dissipation body. A third metal layer thermally connected to a side of the second electrical insulating heat dissipation body is formed at the outer side of the second base plate. A fourth metal layer thermally connected to the second electrical insulating heat dissipation body is formed at another side of the second electrical insulating heat dissipation body. The fourth metal layer is formed with a concave power device accommodating space, and the power device is arranged in the accommodating space.
