Abstract: A thermal print head includes: a substrate; an insulating layer; a wiring layer; a resistor layer; and a protective layer. The substrate has a first surface and a second surface opposite to the first surface. A raised portion protruding toward a side opposite to the second surface and extending along a first direction in a plan view is formed on the first surface. The insulating layer is disposed on the first surface. The wiring layer is disposed on the insulating layer with the resistor layer interposed therebetween. The wiring layer has a bonding pad. A constituent material of the wiring layer is aluminum or an aluminum alloy. The protective layer is disposed on the insulating layer to cover the wiring layer. An opening that exposes the bonding pad is formed in the protective layer.

Abstract: The present disclosure provides a method for manufacturing a diffusion cover that diffuses and transmits light from a semiconductor light-emitting element. The method includes the steps of preparing a base member having an obverse surface and a reverse surface that face away from each other in a thickness direction; forming a lens material on the obverse surface, the lens material containing a photosensitive transparent resin; and removing a portion of the lens material by performing grayscale exposure and development, and forming a lens having a plurality of lens members. Such a configuration can provide a diffusion cover suitable for reducing the manufacturing cost.
