Abstract

An electronic part includes a substrate, a comb-shaped electrode having a plurality of electrode fingers arranged parallel to one another on the upper surface of the substrate, and a protective film formed on the upper surface of the substrate so as to cover the comb-shaped electrode. The protective film has convex portions and concave portions. The convex portions are upwardly convex at the positions corresponding to the electrode fingers, and the concave portions are downwardly concave between the convex portions. The cross section of the protective film in the direction orthogonal to the extending direction of the electrode fingers has a downward convex curve between apex portions of the convex portions.
