A thermal shock tester for electronic components is provided to improve reliability and quality of a product by installing a heating unit at the upper side of a test piece and applying heat shock load similar to the actual environment. A thermal shock tester(100) for electronic components includes a cooling element(130) with a test piece(1) mounted at the upper surface, to cool the test piece; a heating unit(120) installed at the upper side of the test piece to emit the heat to the test piece; and a control unit(190) controlling the cooling element and the heating unit. A lamp screen(122) is arranged between the heating unit and the test piece. The upper end of the lamp screen is placed at the perimeter of the heating unit, and the lower end of the lamp screen includes the whole test piece. The cooling element is a Peltier element. A radiating unit(132) is formed at the lower surface of the cooling element.
