| Zusammenfassung: | A semiconductor laser device has a front surface electrode formed by Au plating, a rear surface electrode formed by Au plating, an anti-adhesive film on the front surface electrode or the rear surface electrode and made of a material that does not react with Au, and a coating film that covers an end face on a light emitting side and an end face opposite the light emitting side. The anti-adhesive films may be located at least at the four corners of the front or rear surface electrode. |
