We present the result of a search for charge asymmetry in B{sup {+-}}{yields}J/{psi}K{sup {+-}} decays using 772x10{sup 6} BB pairs collected at the {Upsilon}(4S) resonance by the Belle detector at the KEKB asymmetric-energy e{sup +}e{sup -} collider. The CP-violating charge asymmetry is measured to be A{sub CP}(B{sup +}{yields}J/{psi}K{sup +})=[-0.76{+-}0.50 (stat){+-}0.22 (syst)]%.
