Claim:
1. A current application device, comprising: a contacting section which includes a plurality of projections for contacting a contact region within an active region of a semiconductor element and for applying a test current thereto, in which the plurality of projections consist of inner side projections for contacting an inner side contact region of the active region and outer side projections for contacting an outer side contact region of the active region surrounding the inner side contact region, the outer side projections surrounding the inner side projections, and an arrangement density of the outer side projections is greater than an arrangement density of the inner side projections; and a pressing section which presses the contacting section against the semiconductor element such that the plurality of the projections contact the contact region, wherein an arrangement area of each of the outer side projections is larger than an arrangement area of each of the inner side projections.
