An electrical component fabrication apparatus, a wiring pattern sheet, electronic device sheet, and a sheet are provided to obtain a highly reliable electronic device with compact size and multiple functions, and protected from pattern deformation, by spreading different kinds of solution and forming pattern deposition. An electrical component fabrication apparatus forms a wiring pattern(1) or electronic device on a paper or paper-based substrate(10) by jetting solid content of solution containing electronic function material by a plurality of jet heads, leaving solid content of the solution on the substrate to form dotted patterns. The jet head jets droplets of the solution using electric energy of mechanical displacement of an electro-mechanical energy conversion element. The droplet has a spherical shape or pillar-like shape extending in the flying direction of the droplet before the droplet collides against a surface of the substrate without accompanying minute droplets at the end of the flying droplet, wherein the droplet of pillar-like shape has a length less than three times its diameter. The shape of the droplet is obtained by observing flying shape of droplet of solution containing the electro-mechanical energy conversion element or equivalent solution using another jet head, adjusting a driving signal from the another jet head to the electro-mechanical energy conversion element, and applying the adjusted signal to the electro-mechanical energy conversion element of the jet head.
