A high-strength, high-precision injection-molded gear in which resin flow regulating projections that partially thicken a web are formed in a position on a side surface side of the web between pin point gates and a teeth section such as to project from the side surface of the web. The resin flow regulating projections are formed such that a center section thereof, the highest in height, is on a radial direction line extending from the pin point gates in the outward radial direction and the height gradually decreases away from the position on the radial direction line in a circumferential direction of the web.
