## Abstract

An optical module includes a circuit substrate and a terminal. The circuit substrate includes a first pattern, a second pattern, a first cover material, and a second cover material. The first pattern electrically is connected to the terminal and formed in a predetermined shape on a first surface of the circuit substrate. The second pattern is formed in a predetermined shape at a position corresponding to the first pattern on a surface opposite to the first surface. The first cover material covers at least a portion of the first pattern to be bent along with bending of the circuit substrate. The second cover material covers at least an end of the second pattern.

## Claims

### Claim 1

An optical module comprising a circuit substrate and a terminal, wherein
the circuit substrate includes:
a first pattern electrically connected to the terminal and formed in a predetermined shape on a first surface of the circuit substrate;
a second pattern formed in a predetermined shape at a position corresponding to the first pattern on a surface opposite to the first surface;
a first cover material that covers at least a portion of the first pattern to be bent along with bending of the circuit substrate; and
a second cover material that covers at least an end of the second pattern, wherein
the first pattern, among wiring patterns on a front surface side of the circuit substrate, is formed in a tear drop shape and
the second pattern, among patterns on a rear surface side of the circuit substrate, is formed in a semicircular shape.

### Claim 2 (depends on 1)

The optical module according to claim 1, wherein the circuit substrate is bent toward the first surface side at the end of the second pattern and the first pattern at a position corresponding to the end.

### Claim 3 (depends on 1)

The optical module according to claim 1, wherein the circuit substrate includes a third pattern formed such that one side thereof is aligned in a same straight line with one side of the second pattern on the surface opposite to the first surface.

### Claim 4 (depends on 1)

The optical module according to claim 1, wherein
a plurality of the first patterns are formed on the first surface such that directions thereof are different from one another, and
a plurality of the second patterns are formed on the opposite surface such that directions thereof coincide with the directions of the corresponding first patterns.

### Claim 5 (depends on 1)

The optical module according to claim 1, wherein the circuit substrate includes a fourth pattern formed on the first surface or the opposite surface and including a bent portion.
