Summary:Provided is an injection-molded resin button, which does not crack or is unlikely to crack at attaching the button to a fabric. This invention relates to a button including a button body having a through-hole at the center thereof. The button body of the button includes a left half part and a right half part, which are segmented left and right by a virtual straight line passing through a gate position, on the button body, corresponding to a gate of a mold for molding the button and the center of the button body. The button body includes one or more concave portions or one or more convex portions on an outer surface of the button body. The button is characterized in that the concave portions or the convex portions are provided asymmetrically in the left and right half parts. The button body includes a nonlinear weld line at least on the outer surface.
