Abstract
A method for manufacturing a card body for a chip card, includes the steps of: supplying a metallic base body with two opposite main faces and a circumferential peripheral face connecting the two main faces, wherein in the base body a module opening for receiving a chip module has already been produced or will still be produced in a module opening zone, and producing a slot on the peripheral face between the two main faces. The slot is formed from the peripheral face up to the module opening or up to the module opening zone. An entry angle (α) of the slot into at least one of the two main faces is not equal to ninety degrees with respect to the main face.
