Magnetic sensor having a main electrical circuit base with a crack forming area

摘要

A magnetic sensor whose electronic components will never become fatally damaged as the result of an external force. In this magnetic sensor, electronic components located near a connector are connected to a base and disposed in such a manner that the longitudinal axis of those electronic components are substantially perpendicular to the longitudinal axis of the base. A crack generating region is formed between the connector electronic component disposed near the connector. The crack generating region yields application of an external force on the base.
