Abstract
A resistor includes materials including copper, nickel, and lanthanum boride. A content of the materials is 40% by mass or more with respect to a total material content of the resistor. The copper includes copper particles having a particle diameter of 2.5 μm or more. In addition, a circuit board includes a substrate, the resistor on the substrate, a metal layer on the resistor and a glass layer on the resistor. Further, an electronic device includes the circuit board and an electronic component on the metal layer.
