Temperature sensor

A temperature sensor comprising:

• a bottomed tubular holder having an opening;
• a temperature detecting device, contained in a bottom part of the holder, having a lead pair connected thereto so as to be introduced from an opening side;
• a filler resin part filling the holder so as to seal the temperature detecting device and extending to the opening;
• a sensor cover comprising a cap part covering the whole opening and a neck part extending from the cap part in a direction generally parallel to the opening of the bottomed tubular holder, wherein the cap part and the neck part are integrated together;
• and
• a guide part, projecting from an edge of the opening in the holder, for guiding leads constituting the lead pair;
• wherein the sensor cover covers the guide part, and the lead pair extending substantially vertically from the filler resin part is bent at substantially right angles toward the guide part.
