A contact force sensor package includes a substrate layer having a vibration detection unit and a pair of first junction pads that are electrical connection ports which are provided on an upper surface of the substrate layer, a flexible circuit substrate layer having a pair of second junction pads provided at a position corresponding to the first junction pads and electrically connected to the first junction pad, a vibration transfer unit having one side contacting the vibration detection unit and the other side contacting a human body and transferring a sphygmus wave of the human body to the vibration detection unit, and an adhesion layer formed between the substrate layer and the flexible circuit substrate layer to reinforce a junction force between the substrate layer and the flexible circuit substrate layer, the adhesion layer being not formed in an area overlapping at least the vibration transfer unit.
