Abstract
To provide a hermetic terminal with an insulating cylinder, the hermetic terminal being applicable to insulation coatings that pose difficulties with known insert molding methods, and being producible in small lots without changing the mold for each change in a ring-like outer metal member, and a manufacturing method thereof. Means for Solving Problem A hermetic terminal includes a ring-like outer metal member including at least one sealing hole, a lead inserted through the sealing hole of the ring-like outer metal member, an insulating material hermetically sealing the lead to the ring-like outer metal member, and an insulating cylinder fitted onto the lead and adhering, at at least an end portion of the insulating cylinder, to the ring-like outer metal member. The insulating cylinder either is formed with one or more circumferential grooves in an outer circumferential wall and includes a sealing member composed of an elastic material in the one or more circumferential grooves, or includes a protrusion formed by extending a portion of an outer diameter portion of the insulating cylinder and surrounding the outer diameter portion.
