Abstract

The invention provides a composite metal sheet produced by joining two metal sheets together, comprising: a projection formed by cutting the two metal sheets along a cutting line and pressing an area surrounded by the cutting line and a reference line in the two metal sheets, with the two metal sheets overlapping each other, with the reference line remaining uncut, with the cutting line extending from and communicating with both terminals of the reference line while forming a predetermined shape together with the reference line, and with the projection formed at one portion of the area in response to pressure applied to the area; hole generated by forming the projection in the two metal sheets; and a joint disposed between an outer peripheral cutting face of the projection and an inner peripheral cutting face of the hole.
