According to one embodiment, an LED module includes a substrate, an interconnect layer, a light emitting diode (LED) package, and a reflection member. The interconnect layer is provided on the substrate. The LED package is mounted on the interconnect layer. The reflection member is provided on a region in the substrate where the LED package is not mounted and has a property of reflecting light emitted from the LED package. The LED package includes a first lead frame, a second lead frame, an LED chip, and a resin body. The first lead frame and the second lead frame are arranged apart from each other on the same plane. The LED chip is provided above the first lead frame and the second lead frame, with one terminal connected to the first lead frame and one other terminal connected to the second lead frame. The resin body covers the LED chip, covers an upper surface, a part of a lower surface, and a part of an end surface of each of the first lead frame and the second lead frame, and exposes a remaining part of the lower surface and a remaining part of the end surface.

According to one embodiment, an LED package includes a first lead frame, a second lead frame, an LED chip, a wire, and a resin body. The first lead frame and the second lead frame are arranged with a space between each other. The LED chip is provided above the first lead frame and the second lead frame. The LED chip has a first terminal connected to the first lead frame and a second terminal connected to the second lead frame. The wire connects the first terminal to the first lead frame. The resin body covers the LED chip as well as a top surface, a part of a bottom surface, and a part of an edge surface of each of the first lead frame and the second lead frame. A remaining portion of each of the bottom surfaces and a remaining portion of each of the edge surfaces are exposed. A chip side angle formed by a top surface of the LED chip and a direction in which the wire is extracted from the first terminal is smaller than a frame side angle formed by the top surface of the first lead frame and a direction in which the wire is extracted from the first lead frame.

A steel sheet for an inner magnetic shield has a ratio of the anhysteretic magnetic permeability in the rolling direction to the anhysteretic magnetic permeability in the transversal direction, which is not higher than 0.7 or not lower than 1.4, preferably not higher than 0.5 or not lower than 2.0. A higher value of the two anhysteretic magnetic permeability values in the rolling direction and in the transversal direction is not lower than 18000. The inner magnetic shield formed of the particular steel sheet has a substantially truncated pyramid body which has a pair of short side members of a screen and a pair of long side members of a screen. The short side members are joined to the long side members at edge portions of the truncated pyramidal inner magnetic shield. The direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to the horizontal plane direction of the short side member. In addition, the direction, in which the anhysteretic magnetic permeability of the steel sheet is the higher value, corresponds to as required to the horizontal plane direction of the long side member.
