An aspect of a mold is for forming therein a cavity for producing a plate-like optical component. The mold includes a stationary mold half, and a movable mold half which forms the cavity in cooperation with the stationary mold half. The stationary mold half includes a first surface mold member for forming a first surface which is one of obverse and reverse surfaces of the plate-like optical component, and a first peripheral mold member for connecting a cavity-side surface of the movable mold half and a cavity-side surface of the first surface mold member. The first peripheral mold member inclines or curves to cause a dimension of the cavity in a direction of a plane approximately parallel to the first surface to become gradually smaller as being closer to the first surface.
