It is aimed to provide a fuse holder with a novel structure capable of improving insertion operability in the fuse holder for holding a plurality of fuses. A plurality of fuse holding portions (26a, 26b) are provided into which main body portions (16, 16) of fuses (12a, 12b) are to be mounted and in which lead portions (14, 14) of the fuses (12a, 12b) are held in a projecting state. Holding positions of the fuses (12a, 12b) by the plurality of fuse holding portions (26a, 26b) are made different from each other in a projecting direction of the lead portions (14) from the main body portions (16) in the fuses (12a, 12b).

A method for creating a dielectric thin-film coating for devices having a fusible element is disclosed. The method comprises mixing insoluble and soluble polymers in solid form and exposing the mixture to heat to create a melt mixture. The melt mixture is then dissolved in a solvent to create a slurry which can then be deposited on the device as a thin-film coating to create an interior insulation layer or an external surface.
