It is an object to provide a highly precise bleeder resistance circuit having an accurate voltage division ratio and a small temperature coefficient of the resistance value and a highly precise semiconductor device having a small temperature coefficient using such a bleeder resistance circuit, e.g., a semiconductor device such as a voltage detector and a voltage regulator. Such characteristic features that the potential of electric conductors on the thin film resistors and electric conductors under the thin film resistors of a bleeder resistance circuit using thin film resistors is made almost equal to the potential of respective thin film resistors and that, when polysilicon is used in the thin film resistor, the dispersion of the resistance value is controlled and the temperature dependency of the resistance value is made lower by thinning the film thickness of the polysilicon thin film resistor are constituted.
