To provide a valve stem and a tire valve capable of connecting electric circuits to each other even while a valve cap is removed.A valve stem (10) has a tubular structure, is fixed in a state of penetrating a valve mounting hole (81H) of a tire wheel (80), and accommodates a valve core (20). The valve stem includes a pair of internal electrodes (11N, 31N) connected to an internal circuit (91) in a tire (82); a pair of external electrodes (11G, 31G) arranged on an outer peripheral surface of a tire outer protruding portion (17) protruding to the outside of the tire (82) in the valve stem (10)and connectable to an external circuit (96) outside the tire (82); and first and second conductive members (11, 31) having the internal electrodes (11N, 31N) and the external electrodes (11G, 31G) and insulated from each other.
