According to one embodiment, a power module includes a metal base, a ceramic substrate, a semiconductor chip, a nut holder housing a nut, an electrode terminal and a casing. The ceramic substrate is connected to an upper surface of the metal base via a lower electrode. The semiconductor chip is located on a first major surface of the ceramic substrate. The electrode terminal includes a bent portion surrounding a nut holder. The electrode terminal includes a first connecting portion extending perpendicularly to the bent portion from one end of the bent portion, and being located on the first major surface via an upper electrode, and electrically connected to the semiconductor chip. A casing is bonded to the metal base to enclose the semiconductor chip and the electrode terminal. An upper end portion of the bent portion of the electrode terminal is exposed to outside of the casing through the opening.
