To prepare a warp one layer three axis braided fabric usable as a substrate for doubled carbon-fibers, etc., having less yarn direction, balanced mechanical strength, thin thickness and excellent flexibility by bonding intersections between oblique yarn groups and warp groups.

This braided fabric comprises oblique yarn groups 3a and 3b which are symmetrical with respect to a warp axis and mutually reversely crossed and a warp group 2 of one layer laminated and arranged in parallel in the direction of the warp at one side of the oblique yarn groups 3a and 3b and the intersections of the yarn groups 2, 3a and 3b are bonded. Preferably, the oblique yarn groups 3a and 3b and the warp group 2 are reinforced yarns such as glass yarns of 10-40 count by tex count.
