Abstract
The semiconductor devicecomprises a housingwhich has a recessin the front surface; a pair of lead electrodeswhich have the distal endsexposed in the recess, protrude from the external surface of the housing, and are bent along the bottom surfaceof the housing; and a semiconductor elementwhich is housed in the recessand is electrically connected to the pair of lead electrodes. The housinghas grooveswhich are formed on the pair of side surfaceswhich adjoin the front surfaceand the bottom surfaceon the right and left sides so as to penetrate the housingfrom the top surfacetoward the bottom surfaceof the housing. The groovespreferably have width substantially equal to the thickness of the lead electrode. The groovesare more preferably formed to be flush with the distal endsof the lead electrode
