To provide a weft knitted fabric, in which cloth is stabilized without causing slipping-out of a polyurethane elastic fiber and non-elastic yarn from a cut part or a sewn part and deformation, slippage, bird-cage, fray, run, spreading, slip-in and curling scarcely occurs and heat-bonded polyurethane elastic fiber is not broken even when expansion and contraction are repeated, improved in durability of knitted fabric.

In the weft knitted fabric using a heat-bonded polyurethane elastic fiber and at least one kind of nonelastic fiber, the heat-bonded polyurethane elastic fiber is formed as a conjugate yarn with other fiber and further, plaiting of the conjugate yarn with the nonelastic fiber is carried out.
