Abstract
A resistor includes a first insulator, a resistive body, a second insulator, a pair of electrodes, and a covering body. The first insulator has a first obverse surface facing in a thickness direction thereof. The resistive body is provided on the first obverse surface. The second insulator covers the resistive body. The pair of electrodes are electrically connected to the resistive body at both sides in a first direction perpendicular to the thickness direction. The covering body is formed on at least one of the first insulator and the second insulator. The covering body has electrical conductivity. The first layer is in contact with at least one of the first insulator and the second insulator.
