1. A floor or wall panel, comprising a substrate and a top layer applied thereon,
wherein the substrate mainly consists of a mineral material, and in that on first and second edges the panel is provided with coupling means that allow first and second panels arranged as said floor or wall panel to be coupled together at respective edges,
wherein in a coupled state there is locking in a vertical direction perpendicular to a plane of coupled panels arranged as said panel, and in a horizontal direction perpendicular to the coupled first and second edges and in the plane of the coupled panels;
wherein said coupling means of the first edge of the first and second edges comprises at least a male part defined by a tongue;
wherein said coupling means on the second edge of the at least two opposite edges comprise at least a female part defined by a groove,
wherein the groove is flanked by a lower lip and an upper lip, wherein the lower lip contains a locking element,
wherein a bottom edge of the tongue comprises a recess,
wherein, in the coupled state of the first and second panels, a contact between the locking element and the recess provides locking of the coupled panels in a direction perpendicular to the coupled first and second edges coupled and parallel to the plane of the coupled panels;
wherein said tongue comprises a sideways projection formed on the respective edge,
wherein the sideways projection on an upper side thereof adjoins a surface or plane of the edge extending substantially vertically, and
wherein a junction of the upper side of the sideways projection with the surface or plane of the edge extending substantially vertically is free from roundings with a radius less than 0.2 mm and/or in that an angle between vertices formed between adjacent surfaces of the junction is always greater than 150°.
