SENSOR UNIT FOR MEASURING BIOMETRIC INFORMATION

The present invention provides a sensor unit in which a sensor inserted into a user's skin along with a needle can be kept being stably inserted into the skin without being affected by the movement of the needle in the process of the needle being separated from the user's skin. The sensor unit according to the present invention, which is attached to the user's skin to measure the user's biometric information, comprises: a sensor that includes a sensor body and an insertion part connected to the sensor body so as to be placed on a different plane from the sensor body and capable of being inserted into the user's skin; a housing base that includes a housing base hole through which the insertion part passes, and supports the sensor body; a housing cap that is coupled to the housing base and covers the sensor body; and a retention protrusion that protrudes from the housing cap to contact the sensor in order to prevent the insertion part from moving backward toward the housing cap.
