Claims

[Scope of Claim for Utility Model Registration] (1) In a heater in which an insulating material is filled around a heating wire arranged in the longitudinal direction within a long sheath, the end of the sheath containing the heating wire and the insulating material inside. Between the high-temperature part, in which the diameter of the sheath and the heating wire are both reduced by reducing the diameter of almost the entire part except for the high-temperature part, and the socket part in which the lead wire is present, A sheath heater comprising a medium temperature section having a large diameter and a large diameter heating wire at the end of the sheath. (2) Claim No. 1 for Utility Model Registration, which consists of a sheath with a high-temperature section in the center, medium-temperature sections at both ends, and a socket via the medium-temperature sections.
Sheath heater described in section. (3) The sheath heater according to claim 1, wherein a socket portion is provided through a medium temperature portion provided at the proximal end of the sheath, which is almost entirely a high temperature portion. (4) The sheath heater according to any one of claims 1, 2, or 3, wherein the sheath is flexible.
