Abstract
A sensor device has a sensing portion, a connector terminal, and a case housing the sensing portion therein and forming a terminal fixing portion. The connector terminal has a fixed portion fixed in the terminal fixing portion of the case. The connector terminal is electrically connected to the sensing portion through a lead for allowing signal transmission between the sensing portion and an external device. A ratio of the volume of the fixed portion of the connector terminal to the volume of the fixing portion of the case is equal to or greater than a predetermined ratio.
