<p>An infrared touch screen, comprising a frame and a touch panel (13); the frame comprises a casing (11) and a circuit board (12); the casing (11), the circuit board (12) and the touch panel (13) are sequentially superimposed; the circuit board (12) is provided with an electronic component (14) and an infrared emitting/receiving element (15) thereon; the infrared emitting/receiving element (15) is located between the circuit board (12) and the touch panel (13). The infrared touch screen is utilized to avoid the loss of the infrared light emitted by an infrared emitting element, thus intensifying the infrared light emitted by the infrared emitting element.</p>
