An electronic control unit has a substrate that includes a terminal connection portion that is a through hole that extends through the substrate from a first surface to a second surface. A resist opening along an outer edge of the terminal connection portion exposes a circuit pattern from a surface resist layer. A plurality of vias are disposed at positions adjacent to the resist opening in a heat receiving area to facilitate the transfer of heat during a soldering process from the first surface to the second surface.
