PROBLEM TO BE SOLVED: To provide a slope shoulder block product which is used for a sloped surface formed by a difference of elevation between a road and a paddy field or an upland field and which is formed in such a complicated shape as to give consideration to a finished surface, and a manufacturing method for the product, which makes a form cost low, which facilitates handling and which dispenses with a change in mixing of concrete even if the products are manufactured at a rate of two pieces per time and two rotations per day. SOLUTION: In terms of the shoulder block A and the manufacturing method therefor, a horizontal part 2 to be mounted on the road is constituted on an upper surface part; a horizontal-part product embedment part 1 of the product serves as a base part; the product is made symmetrical so that a part to be mounted on the road can serve as an upper concrete placing surface; a "truncated chevron-shaped" form enables the two pieces per time to be manufactured by means of an angle of inclination of the product in the construction of the sloped surface in such a manner that a nonslip pattern part is provided in a lower position; and a large opening 9-1 for allowing the passage of steam is constituted in both end frames of the form, so that the concrete can be placed.
