The present invention relates to a crosstalk prevention device of a motion sensor capable of preventing crosstalk that the light generated from a light emitting sensor is reflected from the inner boundary surface of a plastic material or the surface of a window glass and flows into a light receiving sensor. The crosstalk prevention device comprises a plastic material installed on a light emitting sensor, which is installed on one side of the top of a substrate and irradiates an object with light, and a light receiving sensor, which is installed on the other side of the top of the substrate and receives the light reflected from the object; and a diffused reflection surface part which is installed on the surface of the plastic material corresponding to the gap between the light emitting sensor and the light receiving sensor and reflects the light in a diffusing manner to cut off the crosstalk light. |
