Electric connection terminal for a sensor element utilizing ceramics
 An electric connection terminal arranged at a rear end of a sensor element and capable of affording quick and easy connection of the sensor element with a contacting element connected to a lead wire extending into a connector socket or connector insulator accommodating the contacting element for transmitting a signal detected at the front end of the sensor element, is composed of at least two conductive layers, and at least the lowermost layer of the conductive layers is composed of a mixture of a conductive metal and ceramics and/or glass, so that the layers bond firmly with each other and the lowermost layer bonds most firmly to the sensor element, whereby peeling-off of the connection terminal from the sensor element due to friction thereof against the contacting element and repetition of heating and cooling of the sensor element is eliminated.
