PROBLEM TO BE SOLVED: To provide a sticking type biosensor having both flexibility and impact resistance. SOLUTION: A stick-type biosensor is provided so as to overlap a pressure-sensitive adhesive layer having a sticking surface to be stuck to a subject, an elastic electrode, and the opposite surface of the pressure-sensitive adhesive layer to the sticking surface. A base material layer, an electronic device provided on the base material layer and acquiring a biological signal via the electrode, a circuit unit provided on the base material layer and connecting the electrode and the electronic device, and the like. A joint portion for joining the electrode and the circuit portion, a battery provided on the base material layer to supply power to the electronic device, and a battery provided on the base material layer to cover the electronic device and the battery. A hard layer having a flattening layer having a flattened surface, a first surface provided on the flattening layer and superposed on the flat surface, and a second surface opposite to the first surface. The hard layer includes the electrode, the circuit unit, the electronic device, and a shock absorbing layer which is provided on the base material layer and the hard layer and covers the battery. The hard layer is the shock absorbing layer. Harder than.
