    Abstract: A thermal print head includes a semiconductor substrate, a resistor layer with heat generating portions arranged in the main scanning direction, a wiring layer included in a conduction path for energizing the heat generating portions, and a protective layer covering the resistor layer and the wiring layer. The semiconductor substrate includes a projection protruding from the obverse surface of the substrate and elongated in the main scanning direction. The projection has first and second inclined side surfaces spaced apart from each other in the sub-scanning direction. The heat generating portions are arranged to overlap with the first inclined side surface of the projection as viewed in plan view.

    Abstract: Provided is a magnetism detection device by which it is possible to achieve a reduction in size and an increase in accuracy. A magnetism detection device includes: a magneto-impedance element; a magnetic field direction changing body; and a substrate that is formed of a semiconductor material and has an element arrangement recessed portion bottom surface and a back surface that face mutually opposite sides in a thickness direction, and a through-hole that reaches the element arrangement recessed portion bottom surface and the back surface and has a cross-sectional dimension that increases toward the main surface starting from the element arrangement recessed portion bottom surface. The magneto-impedance element is mounted on the element arrangement recessed portion bottom surface, and the magnetic field direction changing body is accommodated in the through-hole.
