The effects of target thickness on emission directions of hot electrons are investigated in the interaction of subrelativistic intensity laser pulses with foil targets. The results show that the emission direction of the hot electrons at the rear side of the target shifts towards the target normal direction as the target thickness increases. It can be seen that the electrostatic field at the rear side of the target surface is the main cause affecting the emission direction of the hot electrons.
