In a current detection apparatus, one or more first plate portions, one or more second plate portions, and one or more third plate portions of one or more magnetic shields are opposed to side surfaces of the one or more protrusions. The one or more protrusions, the one or more magnetic field detection elements, and one or more conductive members are respectively surrounded by the one or more magnetic shields, respectively. Consequently, the current detection apparatus is downsized and has high current detection accuracy.

A semiconductor module is provided with a conductive member having one end, in a longitudinal direction, joined to an electrode of a semiconductor element that is mounted on an insulating substrate, the other end of the conductive member in the longitudinal direction being joined to a component different from the electrode. The conductive member is made up of a metal sheet, and has a bent portion at the one end and at the other end. The bent portion provided at the one end has a cut in a leading end portion, in the longitudinal direction, and an end joining section at which the cut is not present is joined to the electrode of the semiconductor element. As a result, a semiconductor module can be realized that allows combination of increased current capacity with improved reliability.

A cooling apparatus has: an opening formed in a cooling plate for cooling an electronic component; and an electronic component accommodating section formed in the opening. A cooling pipeline is disposed in a manner to surround an outer side surface section of the electronic component accommodating section, whereby the electronic component and the cooling pipeline are arranged at substantially the same height as a top of the cooling plate to realize a low profile. In addition, the electronic component accommodating section, which is joined to the cooling plate, is configured that a side surface section thereof is in contact with a side surface section of the electronic component via a potting material. In this way, an area that contributes to heat radiation is increased.

In the semiconductor module according to the present invention, a conducting member which is used to electrically connect a semiconductor element arranged on a substrate or a bus bar with another electronic component is provided with a structure having flexibility capable of, in a junction with the semiconductor element, reducing the thermal stress due to difference in a coefficient of linear expansion between the conducting member and the semiconductor element, and absorbing dimensional error in objects to be connected. Therefore, the semiconductor module achieves both increased current capacity of the semiconductor device and improved reliability of the semiconductor module.
