## Abstract

A lens holder including a base, a gate mark and a tubular portion is provided. The base includes a plurality of sidewalls, and any two adjacent sidewalls are connected to each other to form an outer edge. A turning corner is formed between every two adjacent sidewalls, and the base includes a chamfer located at a turning corner. The gate mark is disposed at the chamfer. The tubular portion is connected to the base, and the tubular portion extends along the direction away from the base. Besides, a portable electronic device and a manufacturing method of the lens holder are also provided.

## Claims

### Claim 1

A lens holder, comprising:
a base, comprising a plurality of sidewalls, wherein any two adjacent sidewalls are connected to each other to form an outer edge, a turning corner is formed between every two adjacent sidewalls of the sidewalls, and the base comprises a chamfer located at a turning corner;
a gate mark, disposed at the chamfer; and
a tubular portion, connected to the base and extending in a direction away from the base.

### Claim 2 (depends on 1)

The lens holder as claimed in claim 1, wherein the sidewalls are four sidewalls, the outer edge is a quadrangle, the base comprises two chamfers at two of the turning corners, and the chamfers are located on a diagonal of the quadrangle.

### Claim 3 (depends on 2)

The lens holder as claimed in claim 2, wherein the lens holder comprises two gate marks, and the gate marks are respectively disposed at different chamfers of the chamfers.

### Claim 4 (depends on 1)

The lens holder as claimed in claim 1, wherein the sidewalls comprise a first sidewall and a second sidewall, the first sidewall and the second sidewall respectively form a long side and a short side of a quadrangle, and a wall thickness of the first sidewall is greater than a wall thickness of the second sidewall.

### Claim 5 (depends on 1)

The lens holder as claimed in claim 1, wherein a shape of the outer edge is a rectangle.

### Claim 6 (depends on 1)

The lens holder as claimed in claim 1, wherein the sidewalls have a wall thickness d, an angle of the chamfer is substantially 45 degrees, a width of the chamfer is substantially (2−√{square root over (2)})d, and a tolerance of a width of the chamfer is smaller than or equal to 10% of (2−√{square root over (2)})d.

### Claim 7 (depends on 1)

The lens holder as claimed in claim 1, wherein the sidewalls further form an inner edge, the inner edge is a rectangle, and a size of the inner edge is suitable for a light sensing element whose size is smaller than or equal to one inch.

### Claim 8 (depends on 1)

A portable electronic device, comprising a mobile phone, a tablet computer, or a notebook computer, wherein the portable electronic device comprises:
the lens holder as claimed in any one of claim 1;
a lens barrel, disposed on the lens holder; and
at least one lens, disposed in the lens barrel.

### Claim 9

A manufacturing method of a lens holder, comprising:
injecting a molding material into an injection molding mold, wherein the injection molding mold comprises an injection flow channel, and the molding material flows through the injection flow channel and enters a molding cavity of the injection molding mold; and
curing the molding material to form a lens holder in the molding cavity, wherein the lens holder comprises a base and a tubular portion, the base comprises a plurality of sidewalls, any two adjacent sidewalls are connected to each other to form an outer edge, a turning corner is formed between every two adjacent sidewalls of the sidewalls, the base comprises a chamfer located at a turning corners, and the injection flow channel is disposed in correspondence with the chamfer.

### Claim 10 (depends on 9)

The manufacturing method of the lens holder as claimed in claim 9, wherein the sidewalls are four sidewalls, the outer edge is a quadrangle, the base comprises two chamfers at two of the turning corners, and the chamfers are located on a diagonal of the quadrangle.

### Claim 11 (depends on 10)

The manufacturing method of the lens holder as claimed in claim 10, wherein the injection molding mold comprises two injection flow channels, and the injection flow channels are disposed in correspondence with the chamfers.

### Claim 12 (depends on 9)

The manufacturing method of the lens holder as claimed in claim 9, wherein an included angle between the injection flow channel adjacent to one of the sidewalls and the one of the sidewalls is 135 degrees.

### Claim 13 (depends on 9)

The manufacturing method of the lens holder as claimed in claim 9, wherein when a width of the chamfer that is chosen is greater, a cross-sectional area of the injection flow channel that is chosen becomes greater.

### Claim 14 (depends on 9)

The manufacturing method of the lens holder as claimed in claim 9, wherein the sidewalls comprise a first sidewall and a second sidewall, the first sidewall and the second sidewall respectively form a long side and a short side of a quadrangle, and a wall thickness of the first sidewall is greater than a wall thickness of the second sidewall.

### Claim 15 (depends on 9)

The manufacturing method of the lens holder as claimed in claim 9, wherein a shape of the outer edge is a rectangle.

### Claim 16 (depends on 9)
