To provide a lightweight switching valve, electro-hydrostatic circuit, and aircraft that can suppress an overload. A switching valve 30, an electro-hydrostatic circuit 1, and aircraft include: a sleeve 32 on which a plurality of ports are disposed; a spool 34 that is disposed inside the sleeve 32 to be moved in an axial direction AD by a pilot hydraulic pressure to switch between switching lines each serving as a flow channel 30a for hydraulic fluid that is formed by a combination of the ports; a first energizing unit 36 that energizes the spool 34 against the pilot hydraulic pressure; a relief hole 34d that is disposed on the spool 34 to discharge the hydraulic fluid with the pilot hydraulic pressure; a valve body 42 that closes the relief hole 34d; and a second energizing unit 44 that energizes the valve body 42 toward the relief hole 34d of the spool 34 against the pilot hydraulic pressure, and when the pilot hydraulic pressure exceeds a predetermined value, opens the relief hole 34d.
