A valve stem to be mounted to a valve mounting hole of a tire wheel includes a stem body that is pipe-shaped, contains a valve core inside, and has a proximal end to which an electrical circuit unit is fixed, and a cover member made of elastomer and covering an outer side of the stem body. The valve stem includes an engagement groove formed on an outer circumferential surface of a proximal end of the cover member to engage with an opening edge of the valve mounting hole, and a weight adjustment member having a higher specific gravity than the cover member and made of a material different from that of the stem body. The weight adjustment member is embedded in the cover member and positioned closer to a distal end of the cover member than the engagement groove.
