Abstract: To enable stable supplying of a required operation voltage to a load circuit for a long period even if a power generation amount of a power generation part is weak.SOLUTION: In a power supply control circuit 10, a switching control circuit 24 turns on two switches 18 and 20 when intra-terminal voltages VC of a capacitor 16 becomes a threshold value or larger for starting a power supply during charging, and starts a discharge to the capacitor 16 (the supplying the power to a load circuit 14). Then, when the intra-terminal voltages become the threshold value or less for stopping a power supply during a power supply, the switching control circuit turns off the two switches, and stops the discharge (the power supply) of the capacitor and switches it to the charging. A non-liner bypass circuit 22 includes an intermediate node N22, one or a plurality of n diodes D1....Dn, and a resistor R22, and connects the node to a voltage input terminal 24IN of the switching control circuit.SELECTED DRAWING: Figure 1
