Power module and method of manufacturing the same, and power conversion apparatus

A power module comprising:

• a first conductive member;
• a second conductive member spaced away from the first conductive member in a first direction;
• a plurality of conductive wire groups that electrically connect the first conductive member and the second conductive member to each other;
• and
• an insulating sealing member, formed of a homogenous material, that seals at least a part of the first conductive member, at least a part of the second conductive member, and the plurality of conductive wire groups,
• the plurality of conductive wire groups being arranged in parallel in a second direction perpendicular to the first direction, each of the plurality of conductive wire groups being constituted of a plurality of conductive wires,
• the plurality of conductive wires being covered only with the insulating sealing member,
• the plurality of conductive wire groups each including a first bonded portion bonded to the first conductive member and a second bonded portion bonded to the second conductive member,
• in a plan view of the first conductive member, a maximum gap in the second direction between intermediate portions of a pair of the conductive wire groups directly adjacent to each other being larger than a first gap in the second direction between the first bonded portions of the pair of conductive wire groups, and the intermediate portions being located between the first bonded portion and the second bonded portion,
• in the plan view, the maximum gap in the second direction between the intermediate portions of the pair of conductive wire groups being larger than a second gap in the second direction between the second bonded portions of the pair of conductive wire groups wherein the plurality of conductive wires intersect with each other at the intermediate portions.
