摘要

A printed wiring board (10) includes an insulating resinous substrate (11) having an aperture unit (11a), a first terminal unit (12a) and a second terminal unit (12b) consisting of a conductor and formed on top of the resinous substrate (11), and a fuse unit (12c) that electrically couples the first terminal unit (12a) and the second terminal unit (12b) to each other. At least a part of the fuse unit (12c) is disposed over the aperture unit (11a), and in addition, is covered by a porous inorganic covering material (13) having insulating properties.
