1. A conductive paste comprising a metal powder, glass frit, and an organic vehicle, wherein factor A is calculated by Equation 1 below, factor B is calculated by Equation 2 below, and |A−B| is 0.100 or less
A=(Slip velocity×10)/(G′×0.01)  [Equation 1]
B=1/(G″×0.01)  [Equation 2]
(wherein, G′ means the elasticity value when the shear strain is 1%, and G″ means the elasticity value when the shear strain is 90%).
