Abstract
Providing a small-sized acceleration sensor including a vibrator formed of a piezoelectric single crystal, and a weight section connected to the vibrator and supported at a position different from the position of the center of gravity of an assembly of the vibrator and weight section. Two divided electrodes used for detecting an electrical signal are formed on the vibrator and connected to two wiring patterns of the weight section which also functions as a signal detecting substrate, with an anisotropic conductive adhesive. When an acceleration in one direction is applied, an angular moment exerted in the weight section is detected as sliding vibration by the vibrator, and an electrical signal corresponding to the acceleration is output from the electrodes through the wiring patterns.
