Sensor unit for continuous blood glucose measurement

A sensor unit for continuous glucose measurement having one end portion formed to extend in one direction to be inserted into a body for the continuous glucose measurement, the sensor unit comprising:

• a substrate, wherein one end portion of the substrate is formed to extend in one direction to be inserted into the body;
• a first electrode layer stacked on an upper surface of the one end portion of the substrate;
• a first insulation layer stacked to cover an upper surface of the first electrode layer;
• a second electrode layer stacked on an upper surface of the first insulation layer;
• and
• a second insulation layer stacked to cover an upper surface of the second electrode layer,
• wherein the first electrode layer and the second electrode layer are disposed in opposite directions to each other so that one of the first electrode layer and the second electrode layer is exposed at one side surface of both side surfaces of the one end portion of the sensor unit and an other of the first electrode layer and the second electrode layer is exposed at an other side surface of the both side surfaces of the one end portion of the sensor unit.
