Abstract
A sensor device includes a sensor chip and a bonding wire being fixed on a substrate. The sensor device is manufactured by using a binding material made of an adhesive containing a foaming agent that evaporates upon exposure to heat. The binding material reduces its elasticity after a wire bonding process because voids being functional as a cushion are formed by evaporation of the foaming agent.
