## Abstract

A substrate connecting structure includes a first substrate, a second substrate facing the first substrate, and a terminal through which electricity is supplied to the first substrate and the second substrate. The terminal has a first substrate connecting part that is connected to the first substrate from a side opposite from the second substrate, and a second substrate connecting part that is provided by splitting from the first substrate connecting part at an intermediate point in the terminal and connected to the second substrate by extending contactlessly through the first substrate from the side opposite from the second substrate toward the second substrate.

## Claims

### Claim 1

A substrate connecting structure comprising:
a first substrate;
a second substrate facing the first substrate; and
a terminal through which electricity is supplied to the first substrate and the second substrate, the terminal including:
a first substrate connecting part that is connected to the first substrate from a side of the first substrate that is opposite from the second substrate,
a second substrate connecting part that is formed by splitting from the first substrate connecting part at an intermediate point in the terminal and connected to the second substrate by extending contactlessly through the first substrate from the side opposite from the second substrate toward the second substrate,
a connector connecting part, and
a coupling part that couples together the connector connecting part, the first substrate connecting part, and the second substrate connecting part, and the first substrate connecting part and the second substrate connecting part are orthogonal to the coupling part and extend in a direction that is opposite from a direction that the connector connecting part extends.

### Claim 2 (depends on 1)

The substrate connecting structure according to claim 1, wherein the first substrate connecting part and the second substrate connecting part extend along a direction in which the first substrate and the second substrate face each other.

### Claim 3 (depends on 1)

The substrate connecting structure according to claim 1, wherein, among the first substrate connecting part and the second substrate connecting part, at least the first substrate connecting part is provided with a low-rigidity portion.

### Claim 4 (depends on 3)

The substrate connecting structure according to claim 3, wherein:
a width of the first substrate connecting part connected to the first substrate is smaller than a width of the second substrate connecting part connected to the second substrate; and
the first substrate connecting part is provided with, as the low-rigidity portion, a serpentine portion that is a portion alternately extending in a serpentine shape in opposite directions.

### Claim 5 (depends on 3)

The substrate connecting structure according to claim 3, wherein the second substrate connecting part is also provided with a low-rigidity portion, which is a small-width portion that is a portion at which a width of the second substrate connecting part is set smaller than a remainder of the second substrate connecting part.

### Claim 6 (depends on 1)

The substrate connecting structure according to claim 1, wherein the first substrate controls power supply to an electric device, while the second substrate supplies electricity to the electric device under control by the first substrate.
