This voltage detector, which detects whether or not an input voltage is at least a pre-determined threshold voltage, is provided with: a baseline voltage generation unit that generates a baseline voltage; and a comparator to which an input voltage and the baseline voltage are input, and that detects whether or not the input voltage is at least a threshold voltage stipulated by the baseline voltage. The baseline voltage generation unit has: a first read-in MOS transistor having a control gate and a floating gate; a second read-in MOS transistor; a first output MOS transistor; and a second output MOS transistor. 提供一种检测输入电压是否为预先决定的阈值电压以上的电压检测器，该电压检测器具备：基准电压生成部，其生成基准电压；以及比较器，其被输入基准电压和输入电压，检测输入电压是否为根据基准电压而决定的阈值电压以上，其中，基准电压生成部具有：具有控制栅极和浮动栅极的第一写入MOS晶体管、第二写入MOS晶体管、第一输出MOS晶体管以及第二输出MOS晶体管。
