Therefore, it is preferable to form the P-type semiconductor region 44 up to the side surface of the resistance element chip 3 as in the present embodiment in order to completely prevent variations in the current path.
- the resistance value of the resistive element chip 3 is mainly determined by the impurity concentration of the epitaxial layer 42, the area of the opening 44a of the p-type semiconductor region 44, and the semiconductor substrate 41 (upper surface) to the n-type semiconductor region 46 (lower surface). By adjusting the distance to L, the desired value can be controlled.
