A fuel cell stack includes a stack body formed by stacking a plurality of power generation cells. A terminal, an insulating plate, and an end plate are provided at one end of the stack body, and a terminal, an insulating plate, and an end plate are provided at the other end of the stack body. Each of the terminals includes an electrically conductive plate member, and an electrically conductive rod terminal joined integrally with the electrically conductive plate member. A joint portion joining the electrically conductive plate member and the electrically conductive rod terminal is formed by friction stir welding.
