The57 Fe Mossbauer study has been performed for the intercalated compound 2H-Fe0.5-TaSe2 over a temperature range between 14 and 500 K. The intercalation samples 2H -Fex-TaSe2 with high content of Fe（x up to 2）are prepared by electrochemical method for the first time. The Mossbauer measurement shows that iron is in high spin state of Fe3+ and occupies both octahedral and tetrahedral interstices of the Van der Waals gap with same probabitity. The fact that effective masses Meff of iron ions in both sites are close to 57 u and the characteristic temperatures are found to be relatively small （M = 130K

109K respectively） is attributed to the weak forces on Fe3+.
