In a high-voltage detection circuit (10) for detecting a high voltage (VP) output from a high-voltage generation circuit (14), an output of the high-voltage generation circuit is dropped in voltage by a high-voltage drop circuit (13) to output a dropped voltage (VO), a reference-voltage generation circuit (11) generates a reference voltage (Vref) of a comparatively-high potential using the the high voltage (VP) as its power source, and a comparison circuit (12) compares the dropped voltage (VO) with the reference voltage (Vref) to control a high-voltage level.
