Abstract
A weight sensor includes a deformable body, a first strain resistor provided on an outer side surface of the deformable body, and a pressing member applying a load to the deformable body. The deformable body includes a tubular portion having a tubular shape extending along a center axis and surrounding the center axis, and a projection projecting from an inner surface of the tubular portion. The pressing member moves along the center axis so as to apply a moment to the tubular portion. The resistances of the strain resistors change greatly, allowing the weight sensor to measure a load with high sensitivity.
