Abstract
A liquid-condition detection sensor () including a sensor element (), at least a portion of which contacts a urea aqueous solution; connection terminals () fixedly attached to the sensor element (); connection cables () which electrically communicate with the concentration sensor element () via the connection terminals (); an inner tube () which holds the concentration sensor element () at a distal end portion () by use of a holder member () and surrounds a portion of the connection cables () and the entire connection terminals (); and a separator formed from a material having rubberlike elasticity () including a terminal-inner-tube-insulating portion () which intervenes between the connection terminals () and the inner tube () to thereby insulate the connection terminals () and the inner rube () from one another.
