## Abstract

In a camera module (51), a lid glass (15) protrudes from a sensor cover (14) toward an image pickup lens (1), and a base section (9) includes an overhanging part (9b) overhanging in such a manner as to cover part of the lid glass (15).

## Claims

### Claim at position 1

1-8. (canceled)

### Claim 9

A camera module comprising:
an image pickup element;
a lens provided above the image pickup element;
a housing section which has an opening facing the lens and which houses the image pickup element; and
a translucent member which closes the opening,
the housing section having a protrusion which protrudes in such a manner as to cover part of the image pickup element,
the translucent member being fixed on the protrusion,
the protrusion having a side surface which is inclined so as to be away from a center of the opening gradually in a downward direction from a side of the lens toward a side of the image pickup element.

### Claim 10 (depends on 9)

The camera module as set forth in claim 9, wherein the housing section is provided with a recess covering the opening, the recess having a side wall which is not in contact with a side wall of the translucent member.

### Claim 11 (depends on 9)

The camera module as set forth in claim 9, wherein the housing section is provided with a recess covering the opening, a space being provided between a side wall of the recess and a side wall of the translucent member.

### Claim 12 (depends on 11)

The camera module as set forth in claim 11, wherein the space surrounds the translucent member.

### Claim 13 (depends on 9)

The camera module as set forth in claim 9, wherein part of the protrusion and part of the image pickup element face each other.

### Claim 14 (depends on 13)

The camera module as set forth in claim 13, wherein the protrusion includes a first protrusion and a second protrusion in a cross section of the protrusion, each of the first protrusion and the second protrusion facing the image pickup element.

### Claim 15 (depends on 9)

A camera module as set forth in claim 9, further comprising:
a movable section which holds the lens; and
a fixed section, fixed in a different position on the housing section from the translucent member, which drives the movable section,
the translucent member having an upper surface that is closer to the lens than a mounting surface on the housing section on which the fixed section is fixed.

### Claim 16 (depends on 15)

The camera module as set forth in claim 15, wherein the fixed section has an overhanging part overhanging in such a manner as to cover part of the translucent member.
