Claim 8:
9. An insulating component, comprising:
an insulating substrate including a upper surface, a side surface, a bottom surface opposite to the upper surface, and a groove located continuously from the upper surface to the side surface;
a metal layer located on the insulating substrate to which a conductive connecting terminal is joined;
wherein the metal layer including:
a first metal layer located on the upper surface and extended in the first direction; and
a second metal layer located on an inner surface of the groove and continuous with the first metal layer;

wherein the groove includes a first region intersecting the upper surface, a second region located below and connecting to the first region;
a width of the second region in a second direction perpendicular to the first direction is smaller than a width of the first region in the second direction as viewed from above;
the second region has a ridge on the inner surface of the groove portion; and
the ridge protrudes on an opposite side of the inner surface.
