A valve stem includes: a pair of internal electrodes connected to an internal circuit; a pair of external electrodes connectable to an external circuit; first and second conductive members having the internal electrodes and the external electrodes and insulated from each other; a conductive stem main body forming the first conductive member; a core fitting portion; and an inner sleeve fitted in the stem main body. The inner sleeve includes a conductive inner sleeve main body forming the second conductive member, and an insulating layer covering an outer side surface of the inner sleeve main body to insulate between the inner sleeve main body and the stem main body. The stem main body has a side surface through-hole laterally penetrating the stem main body and closed with an end portion of the inner sleeve, the side surface through-hole providing the external electrode of the second conductive member.
