摘要： PROBLEM TO BE SOLVED: To provide a superior plug-in type fuse, in which improvement of spring characteristics of a pressure spring at both female terminals is realized, and which can accommodate high rating by reducing circuit resistance. SOLUTION: In the plug-in type fuse 31, a fuse body 33, inserted from an upper opening 34, is accommodated and held within a housing 34 made of insulation resin. In the fuse body 33, a pair of female terminals 41, 41 fitting and connecting an opposite-side tab terminal 39 are molded integrally on both ends of a fusible conductor 37, having a second fusion section 37b with a metal plate of material having high conductivity. The female terminals 41 is provided with a pair of peripheral walls 41b, 41b bent and formed so as to define a fitting space 45 into which the opposite-side tab terminal 39 is fitted against a back plate 41a formed, by extending the end of the fusible conductor 37. A pressure spring 43 for pressurizing and energizing the opposite-side tab terminal 39 inserted into the fitting space 45 against the back plate 41a is formed as a separate body from the fuse body 33 with material having high spring characteristics, and is mounted on a mutual butt side of the peripheral walls counterposing the back plate 41a.
