A method for manufacturing a sensor unit includes the steps of: Step 1 is providing a substrate having sensor unit areas. Each sensor unit area is partitioned into two individual circuit areas. A signal emitting device and a signal detecting device are respectively disposed on the two circuit areas. Step 2 is forming a packaging structure to cover the two circuit areas, the signal emitting device, the signal detecting device, and a cutting area between the two circuit areas using a mold. Step 3 is cutting the packaging structure along the cutting area to form a separation cut groove. Step 4 is assembling a separation member onto each sensor unit area. The separation member is disposed on the separation cut groove so that the signal emitting device and the signal detecting device on the same sensor unit area are isolated from each other. |
