A lamination of a resilient and elongate magnetic sheet and a conductor strip is rolled up around a magnetic winding core to form a roll, and then the roll is sintered to produce an intermediate product. The conductor strip has both ends at both sides of the magnetic sheet so that both ends of the conductor strip are respectively exposed at both sides of the roll. Terminal electrodes are respectively attached to the both sides of the intermediate product to complete the chip coil. Another magnetic sheet may be provided to make the thickness of the lamination substantially uniform throughout the entire area. A second conductor strip may be provided in the lamination so that a coil having a tap can be actualized. The shrinkages of the winding core and the magnetic sheet are selected so that a desirable sintered product will result without suffering from delamination or cracks. The electrical characteristics of the coil may be changed by varying the amounts of components and changing additives in each of the materials respectively used for the winding core and the magnetic sheet.

A resin-bonded graphite body having controlled crystalline orientation and a density of at least 2.05 g/cm.sup.3, the body comprising 3 to 12 weight % of a thermosetting resin and 88 to 97 weight % of a carbonaceous powder, is provided which includes at least 50 weight % of natural crystalline graphite powder. The body has a high transverse strength and a very low electrical resistance in the direction parallel to the direction of the crystalline orientation, and is thus suitable for a dry battery electrode.

An overtemperature and overcurrent resistor fuse has a resistor body with finely divided conducting powder and silica powder dispersed in an organic flux and resin. The conducting powder has a melting temperature in the range from 60.degree.C to 350.degree. C. This overtemperature and overcurrent resistor fuse has a relatively low electrical resistance below a selected melting temperature and has an irreversible abrupt increase of electrical resistance above the selected melting temperature range caused by serious overload or overheating conditions.
