Patent ID: 8092086

Claim:
A temperature sensor comprising: a temperature-sensing element comprising a temperature-sensing portion and an element electrode wire connected to the temperature-sensing portion and extending rearwardly from the temperature-sensing portion; a sheath member comprising a sheath tube and a sheath core wire extending from a front end of the sheath tube, the sheath core wire being joined to the element electrode wire to form a first joint portion from the temperature sensing portion, the sheath tube being positioned around at least a portion of the sheath core wire for insulating and holding the sheath core wire; an enclosing member made of metal, comprising a closed-bottomed tube having a bottom portion at one end, and enclosing at least the temperature-sensing element and the joint portion; and a holding material filling at least a portion of a space enclosed by the bottom portion of the enclosing member and holding, in the bottom portion of the enclosing member, at least the temperature-sensing portion, the element electrode wire, and the first joint portion from the temperature sensing portion; the element electrode wire including a bend at an intermediate portion of the element electrode wire between the temperature-sensing portion and the first joint portion from the temperature sensing portion, the bend for mitigating a shearing stress applied to the joint portion as a result of thermal contraction.
