Abstract
A sensor is provided with a sensing unit for generating electrical signals responding to a physical quantity, multiple terminals for an electrical connection with an external, multiple signal wires for transmitting the electrical signals to the terminals, a connector housing where the terminals are accommodated, and an electrically isolating case, to which the terminals are fixed. The terminals and the electrically isolating case are inserted into the connecter housing. Thus, the connecter housing can be singly formed without being insert-molded. Accordingly, the manufacture performance of the sensor can be improved.
