The invention discloses a single anchor point support type silicon micro-machined resonant accelerometer which comprises a lower layer glass substrate, a lead wire layer is formed by sputtering metal on an upper surface of the lower layer glass substrate, a bonding layer is arranged on the glass substrate and the lead wire layer, a silicon structure layer is suspended above the glass substrate via the bonding layer, a movable structure of a whole upper layer silicon structure layer is supported via an only anchor point, the upper layer silicon structure layer comprises a fixed support framework and two upper layer silicon micro-mechanic substructures which are respectively first and second upper layer silicon micro-mechanic substructures, the first and second upper layer silicon micro-mechanical substructures are arranged in a vertical direction and are symmetric about a horizontal axis of an upper layer silicon micro-mechanic structure, and differential structures formed by the first and second upper layer silicon micro-mechanical substructures make up a group of acceleration measurement modules. The single anchor point support type silicon micro-machined resonant accelerometer can effectively suppress effects caused by mismatch in material attributes of substrate material and silicon material, and residual stress which is generated during bonding processes and thermal stress which is generated when environment changes can be eliminated.
