An electronic pen includes a tubular casing, and a first coupling member and a second coupling member that are coupled to each other in a hollow portion of the casing in an axial direction of the casing. In the axial direction, the first coupling member and the second coupling member are coupled to each other, and in a coupling portion between the first coupling member and the second coupling member, a welded portion that attaches the first coupling member and the second coupling member to each other is formed. The first coupling member is coupled to a core. The second coupling member holds a printed circuit board. The core of the core-side component is made of a conductive material. The second coupling member includes a conductor that supplies, to the core, a signal from a signal transmitting circuit on the printed circuit board with a battery.

Electronic pen and cartridge for electronic pen

An electronic pen includes a tubular casing, and a first coupling member and a second coupling member that are coupled to each other in a hollow portion of the casing in an axial direction of the casing. In the axial direction, the first coupling member and the second coupling member are coupled to each other while partially overlapping each other, and in a coupling portion between the first coupling member and the second coupling member, a welded portion that attaches the first coupling member and the second coupling member to each other is formed.

A position indicator includes: a chassis; a substrate disposed inside the chassis; a coil; capacitors disposed on the substrate; interconnects disposed on the substrate such that each at least partially connects a respective one of the capacitors to the coil in parallel; and pairs of land patterns. Each pair of land patterns includes a first land pattern and a second land pattern. Each of the interconnects has a first end connected to a first end of the coil and a second end connected to a second end of the coil, and is connected to one of the capacitors. The pairs of land patterns are disposed such that each of the interconnects is at least partially interposed between the first land pattern and the second land pattern of one of the pairs of land patterns.

Position indicator and manufacturing method thereof

An external preparation characterized by comprising, as selected from gallic acid derivatives of the following formula (I), wherein Rrepresents a hydrogen atom, an alkali metal, an alkaline earth metal, an ammonium salt, or an alkyl or alkenyl group having from 1 to 18 carbon atoms and R, R, and Rindependently represent a hydrogen atom, an hydroxyl group, an alkoxy group having from 1 to 18 carbon atoms, a polyoxyethylene group, a polyoxypropylene group, or a residue of a monosaccharide, a disaccharide, or an oligosaccharide; 90 wt % or over of one or more gallic acid derivatives (A) wherein two of R, R, and Rin the formula (I) independently represent a residue of a monosaccharide, disaccharide, or oligosaccharide and from 0.001 wt % to less than 10 wt % of one or more gallic acid derivatives (B) wherein one of R, R, and Rrepresents a residue of a monosaccharide, disaccharide, or oligosaccharide, each based on the total content of the gallic acid derivatives.
