A formed article (10) for a vehicle body structural member includes: a first gradually varying portion (13) that is curved around an axis extending in a width direction of a top wall portion (11)and the width of the top wall portion (11) varies; and a second gradually varying portion (21, 26) in which the width of a leg wall portion (19) varies so as to cancel the variation in the width of the top wall portion (11) in the first gradually varying portion (13). The shape of a gradually-varying-portion ridge (14, 16) that is a boundary between the first gradually varying portion (13) and the second gradually varying portion (21, 26) is made substantially the same both in a plan view that is viewed along the thickness direction of the top wall portion and in a side view that is viewed along the width direction of the top wall portion.
