Power converter

A power converter comprising:

• a semiconductor module comprising:
• a converter component that includes at least one semiconductor element for power conversion;
• and
• a plurality of power terminals protruding from the converter component in a first direction serving as a protrusion direction, and each having a predetermined thickness in a second direction serving as a thickness direction;
• and
• a plurality of busbars connected to the respective power terminals,
• the power terminals including at least one narrow power terminal, the at
• least one narrow power terminal comprising:
• a first portion having a first thermal resistance and a first rigidity;
• and
• a second portion having a second thermal resistance and a second rigidity, the second thermal resistance being higher than the first thermal resistance, the second rigidity being smaller than the first rigidity.
