In order to make it possible to have a simple structure and a small size, to deform flexibly, and to be used for various applications without restricting usage, a capacitive dynamic quantity sensor element includes a base material 2 that has an electric insulating property and dynamic elasticity and has at least a pair of facing surfaces, four electrodes 4 that are disposed on one surface of the pair of surfaces of the base material 2, and four electrodes 4 that are disposed on the other surface of the pair of surfaces to face the four electrodes 4 on said one surface respectively, and detects capacitance between the electrodes 4 of each combination of two electrodes selected from the electrodes 4.
