## Abstract

A mechanism excellent in assembly workability of a light emitting device and capable of stably protecting a soldered portion between a lead wire and the electrode part of a flash discharge tube against static electricity. A strobe panel scatters light emitted by the flash discharge tube. A strobe base holds the strobe panel. A strobe cover is attached to the strobe base in a manner covering the flash discharge tube and the strobe panel. An elastic case shields between a gap between the strobe base and the strobe cover meet and the electrode part of the flash discharge tube, and between another gap between the strobe base and the strobe panel and the electrode part of the flash discharge tube. A non-conductive elastic adhesive is filled between the elastic case and the electrode part in a manner sealing the electrode part.

## Claims

### Claim 1

A light emitting device comprising:
a light emitting element having an electrode part to which a lead wire is connected;
a panel member configured to scatter light emitted by said light emitting element;
a base member configured to hold said panel member;
a cover member attached to said base member in a manner covering said light emitting element and said panel member; and
a shielding member formed of a non-conductive material and configured to shield between a first gap formed at an area where said base member and said cover member meet and said electrode part of said light emitting element,
wherein said shielding member shields between a second gap formed at an area where said base member and said panel member meet and said electrode part of said light emitting element,
wherein a non-conductive adhesive is filled between said shielding member and said electrode part of said light emitting element such that said electrode part is sealed, and
wherein said shielding member is secured to said panel member and said base member, by being fitted in grooves formed respectively in said panel member and said base member.

### Claim 2 (depends on 1)

The light emitting device according to claim 1, wherein said shielding member is formed of an elastic and heat-resistant material.

### Claim 3

An image pickup apparatus comprising:
a light emitting element having an electrode part to which a lead wire is connected;
a panel member configured to scatter light emitted by said light emitting element;
a base member configured to hold said panel member;
a cover member attached to said base member in a manner covering said light emitting element and said panel member; and
a shielding member formed of a non-conductive material and configured to shield between a first gap formed at an area where said base member and said cover member meet and said electrode part of said light emitting element,
wherein said shielding member shields between a second gap formed at an area where said base member and said panel member meet and said electrode part of said light emitting element,
wherein a non-conductive adhesive is filled between said shielding member and said electrode part of said light emitting element such that said electrode part is sealed, and
wherein said shielding member is secured to said panel member and said base member, by being fitted in grooves formed respectively in said panel member and said base member.

### Claim 4 (depends on 3)

The image pickup apparatus according to claim 3, wherein said shielding member is formed of an elastic and heat-resistant material.
