Easy, the minimum gap size between electrodes, from the information supplied, is zero.
If that is not what you want, you will have to provide more information - but usually you want the smallest gap without getting a spark ... which depends on the material separating, and the potential difference between, them.
iirc The shape of the electrodes can matter too.

Thanks

you are right sir the smallest gap without getting a spark. the material is copper & Silver Rivet but the material is same for both side.

I am working on Power Relay.. in that NO & NC Both Connection. when NO Is open that time NC is close but i have to make safe distance for NC for sparking...problem

I am not getting the meaning of iirc The shape. but in my rivet one with flat surface and another has a little curve.

Look up "Paschen Curves"
