PROBLEM TO BE SOLVED: To provide a flat yarn cloth used for reinforcement lamination, having a low thermal contraction coefficient and having good adhesive property to polyethylene-based films or nonwoven fabrics. SOLUTION: This flat yarn cloth used for reinforcement lamination uses as warps and wefts composite tape yarns each composed from an intermediate layer comprising polypropylene and both outer layers comprising the following resin composition. The resin composition comprises 20-60 wt.% of a polypropylene-based resin and 40-80 wt.% of an ethylene-α-olefin copolymer produced using a metallocene catalyst having the following properties (1)-(4). (1) A melt flow rate of 0.1-10 g/10 min. (2) A density of 0.90-0.94 g/cm3. (3) The maximum peak temperature (Tm) of 80-125 deg.C by DSC. (4) A mol.wt. distribution (Mw/Mn) of 1.8-3.5.
