Abstract: A circuit module comprises a substrate module, an electronic component, and a first conductive joining member. The substrate module includes a circuit substrate having an upper main surface and a lower main surface, an insulating member covering the upper main surface of the circuit substrate, an insulating member covering the upper main surface of the circuit substrate, and a first metal pin that passes through the insulating member parallel to a vertical axis and is electrically connected to the circuit substrate. The first metal pin has a first exposed portion. The first exposed portion is exposed from the insulating member to face a right direction. A first outer electrode has a left projecting portion projecting in a left direction from the left surface. A first conductive joining member joins the first exposed portion and the left projecting portion to each other.

Abstract: An object of the present invention is to provide a technique of suppressing precipitation of an anthocyanin pigment in a range other than the highly acidic range. The present invention provides an anthocyanin pigment preparation, comprising: an anthocyanin pigment; and an emulsifier, wherein the pH when the anthocyanin pigment preparation is diluted with water or dissolved in water so that a color value becomes 10 is more than 3.
