The present invention addresses the problem of providing a power device comprising a terminal-holding member excellent in insulating properties. The present invention relates to a power device having a power element, a terminal, and a terminal-holding member composed of a liquid crystalline polyester, wherein the liquid crystalline polyester is a liquid crystalline polyester having a repeating unit (1) derived from an aromatic hydroxycarboxylic acid, a repeating unit (2) derived from an aromatic dicarboxylic acid, and a repeating unit (3) derived from an aromatic diol, and the content of a repeating unit derived from isophthalic acid in the liquid crystalline polyester is 0 to 7 mol % relative to the total amount of all repeating units of the liquid crystalline polyester.
