Classification: CPC H | IPC H

Claim 0:
1. A wiring substrate that includes an element mounted thereon, the element including a first end and a second end, and that functions as a path for a current flowing between the first end and the second end to flow outside of the element, the wiring substrate comprising:
a first conductive plate, a second conductive plate, and a first insulator,
wherein the first conductive plate includes:
a first main surface on which the element is mounted, and that is connected to the first end, and
a second main surface whose position is different from a position of the first main surface of the first conductive plate in a thickness direction of the first conductive plate,

the second conductive plate includes:
a first main surface on which the element is mounted, and that is connected to the second end, and
a second main surface whose position is different from a position of the first main surface of the second conductive plate in a thickness direction of the second conductive plate,

the first insulator includes:
a first portion that separates the first conductive plate and the second conductive plate from each other, and
a second portion that is continuous with the first portion, and covers at least a portion of the first main surface of the first conductive plate, and

the first portion includes an end portion that protrudes from the second main surface of the first conductive plate to the opposite side of the first main surface of the first conductive plate or from the second main surface of the second conductive plate to the opposite side of the first main surface of the second conductive plate.
