PROBLEM TO BE SOLVED: To provide a polyarylene sulfide composition which excels in thermal conductivity particularly useful in applications for electric parts such as electric/electronic parts and/or automobile electrical components, dimensional stability, heat resistance, mold release properties, low gas properties, and melt flowability and reduces the anisotropy of thermal conductivity. SOLUTION: This polyarylene sulfide composition comprises (a) a polyarylene sulfide, (b) a low melting point alloy having a liquidus temperature of not lower than 300°C and a solidus temperature of 150-250°C, (c) a high purity magnesite powder which is magnesite having magnesium carbonate as the major component and has a magnesium carbonate content of 98-99.999 wt.%, (d) at least one thermal-conductivity filler selected from the group consisting of a metal powder having a melting point of not lower than 400°C, a scaly boron nitride powder having a hexagonal structure, a carbon fiber, and graphite, and (e) carnauba wax.
