1. A body attachable unit for continuous glucose measurement, the body attachable unit configured to be insertedly attachable to a body by an applicator for the continuous glucose measurement, the body attachable unit comprising:
a housing, wherein a bottom surface of the housing is to contact a skin;
a printed circuit board (PCB) disposed inside the housing;
a sensor unit installed in the housing, wherein one end portion of the sensor unit outwardly protrudes from the bottom surface of the housing to be inserted into the body when the housing contacts the skin, and an other end portion of the sensor unit is disposed to be separated from an electrical contact point of the PCB in the housing; and
a pressurizing operation module configured to pressurize the other end portion of the sensor unit to be contacted to the electrical contact point of the PCB according to manipulation of a user,
wherein a shape of at least a part of the other end portion of the sensor unit is configured to be deformable by the pressurizing operation module such that the other end portion of the sensor unit contacts to the electric contact point of the PCB,
wherein the pressurizing operation module comprises a movable pressurizing body movably coupled to the housing, and configured to be movable in a direction pressurized by a pressurizing force of the user,
wherein at least a part of the other end portion of the sensor unit is configured to be transformable by being pressurized by the movable pressurizing body according to movement of the movable pressurizing body to be contacted to the electrical contact point of the PCB,
wherein a protruding guide unit configured to be protruded along a movement direction of the movable pressurizing body is formed at the movable pressurizing body,
wherein a locking hook is formed at an outer circumferential surface of the protruding guide unit,
wherein an interlocking projection is formed at the housing to be interlockable with the locking hook of the protruding guide unit in the state that the movable pressurizing body is moved toward the direction pressurized by the pressurizing force of the user, and
wherein a position of the movable pressurizing body is fixed by interlocking the locking hook to the interlocking projection.
