An insulating component includes an insulating substrate, a metal layer, a bond, and a lead terminal. The plate-like insulating substrate has a groove continuous from its upper to side surfaces. The metal layer includes a first metal layer on the upper surface of the insulating substrate and a second metal layer on an inner surface of the groove continuous with the first metal layer. The bond is on an upper surface of the metal layer. The lead terminal is on an upper surface of the first metal layer with the bond in between, and overlaps the grooves. The bond includes a first bond fixing the lead terminal to the first metal layer and a second bond on an upper surface of the second metal layer continuous with the first bond. The groove includes an inner wall having a ridge. The second bond is between the ridge and the lead terminal.
