description PROBLEM TO BE SOLVED: To provide an acceleration sensor element that is miniaturizable while maintaining sensitivity. SOLUTION: The sensor element 20 includes: a weight 11 having a recess 21 opened downward; a frame-shaped fixing part 13 enclosing the weight 11; a beam 12 with one end connected to the fixing part 13, and the other end connected to the weight 11; a resistance element 15 provided on the beam 12, whose resistance value is changed following bending of the beam 12; a weight member 11 comprising a material having a greater specific gravity than a material of the weight 11, to be buried into the recess 21; and a lid member 16 fixed to the weight 11 with an opening of the recess 21 blocked.
