    Abstract: An object is to provide a temperature sensor having improved fracture strength of a weld zone between an element electrode wire and a sheath core wire. In the temperature sensor, with the weld zone being viewed from a direction from which a contact portion between the element electrode wire and the sheath core wire is visible, there is determined a center point of a line segment connecting a point located on the surface of the weld zone and closest to a temperature-sensing portion and a point located on the surface and farthest from the temperature-sensing portion. When a section of the weld zone is taken orthogonally to the axial direction of a sheath member and in such a manner as to pass through the center point, as viewed on the section, L/D is equal to or greater than 0.6, wherein D represents the diameter of the element electrode wire, and L represents the length of a chord connecting a first weld point and a second weld point, the first weld point representing an intersection of the weld zone and the circumference of the element electrode wire located toward a side from which the laser beam is radiated, and the second weld point representing an intersection of the weld zone and an imaginary circumference which starts from the first weld point and traces, within the weld zone, the circumference of the element electrode wire as viewed before welding.
