Abstract
A resistor device can be cheaply produced without a troublesome processing and without a complicated manufacturing process, obtaining a construction which has a stable efficiency. The resistor body 24 which can change a resistance value by selecting a plurality of end portions is clamped between a pair of the insulation sheets 31a, 31b. Moreover, both of these insulation sheets 31a, 31b are clamped between a pair of cover plates 32a, 32b. The end portion of the resistor body 24 is connected to the electric conductor piece 26 fixed to the base 25 and the first, second, and fourth terminals 27, 28, 30. The fuse 43 is provided between the electric conductor piece 26 and the third terminal 29.
