PROBLEM TO BE SOLVED: To achieve satisfactory light reflecting performance even without applying any undercoat layer by injection-molding a composition containing a polyphenylene sulfide resin, potassium silicate whisker and a granular inorganic filler so as to provide a lamp reflection mirror. SOLUTION: In a head lamp 1 for a vehicle, a lighting fixture body 2 and a front lens 4 attached to the front opening of the lighting fixture body 2 defines a lighting chamber 6, in which a reflection mirror 3 and a bulb 5 are housed. The reflection mirror 3 is obtained by injection-molding a composition containing 30-50wt.% of a polyphenylene sulfide resin, 5-30wt.% of potassium silicate whisker and 20-65wt.% of a granular inorganic filler. Furthermore, the reflection mirror 3 is divided into a plurality of faces, on the boundaries of which steps are desirablly formed. |
