PROBLEM TO BE SOLVED: To provide a cement mortar tile which secures a sticking strength by displaying a successful interlocking effect between a combination of a deep groove/a shallow groove of a lattice-like back foot groove and an adhesive such as a tile sticking mortar. SOLUTION: This cement mortar tile has the back foot groove, formed on the back, which consists of the lattice-like back foot groove molded of a net 2 of a lattice knitted structure obtained by cross-knitting pieces of wire 2a and 2b. In addition, the lattice-like back foot groove has the deep groove 7a formed of a wire part of a cross-knitted part 6 of the net 2 and also the shallow groove 7b molded of the wire part extending between the cross-knitted parts 6.
