The present invention provides a temperature-sensitive pellet type thermal fuse, a manufacturing method of the temperature-sensitive pellet type thermal fuse and a mounting method of the temperature-sensitive pellet type thermal fuse which, when the fuse is mounted on a temperature control target object having a planar portion, can ensure a high heat response speed, can decrease the difference in a heat response time for every product, can ensure high operational reliability, reduces the number of parts, and can reduce a manufacturing cost. A temperature-sensitive pellet type thermal fuse includes: an elongated case which has a hollow portion in the inside thereof; a first lead line which is arranged on one longitudinal end portion side of the elongated case along the longitudinal direction; a second lead line which is arranged on the other longitudinal end portion side of the elongated case along the longitudinal direction; and a movable contact which is arranged in the hollow portion and is brought into contact with the second lead line which is always biased in the move-away direction by way of a molten pellet arranged in contact with the first lead line, the movable contact being movable away from the second lead line due to a biasing force when a temperature of a temperature control target object arrives at a predetermined temperature or more and the molten pellet is melted thus cutting off a power source circuit, wherein the elongated case includes a planar portion which is brought into face contact with a planar portion of the temperature control target object. |
