摘要： A module includes a substrate, a first component, a sealing resin, and a shield film. The substrate is provided with a first surface. The first component is mounted on the first surface. The first component is sealed with the sealing resin at least from a lateral side. The first component is provided with an exposed surface. The exposed surface is exposed through the sealing resin on a side opposite to the substrate. The shield film is made of metal and covers the first component and the sealing resin. The shield film is provided with a first contact portion. The first contact portion is in contact with the exposed surface. The first contact portion includes a layer formed from a plurality of crystal grains. The plurality of crystal grains are different in longitudinal direction from one another when they are viewed from a direction orthogonal to the first surface.

摘要： A radio frequency circuit includes a power amplifier, which supports Power class 2, a first filter, which is connected to the power amplifier, which supports Power class 3, and which has a passband including the uplink operating band of Band A for FDD, a second filter, which is connected to the power amplifier, which supports Power class 3, and which has a passband including the uplink operating band of Band A, and a third filter, which is connected to the power amplifier, which supports Power class 2, and which has a passband including Band B for TDD. When a transmit signal in Band A, which supports Power class 2, from the power amplifier is to be output, a transmit signal in Band A is split for output to the first filter and the second filter. When a transmit signal in Band B, which supports Power class 2, is to be output, a transmit signal in Band B is output from the power amplifier to the third filter.

摘要： A filter device includes a piezoelectric substrate, and multiple serial arm resonators and at least one parallel arm resonator on the piezoelectric substrate. First serial arm resonators of the multiple serial arm resonators include a silicon oxide film with a relatively large film thickness. Another of the multiple serial arm resonators is a second serial arm resonator including a silicon oxide film with a relatively small film thickness. Anti-resonant frequencies of the first serial arm resonators are lower than that of the second serial arm resonator. An aspect ratio is determined by a ratio of an intersecting width of electrode fingers of an IDT electrode relative to a number of electrode fingers of the IDT electrode. Aspect ratios of the first serial arm resonators are higher than that of the second serial arm resonator.

摘要： A secondary battery includes an electrode wound body, a positive electrode current collector plate, a negative electrode current collector plate, an electrolytic solution, and a battery can. The electrode wound body includes a positive electrode and a negative electrode. The positive electrode includes a positive electrode current collector, and a positive electrode active material layer covering the positive electrode current collector. The electrolytic solution includes an impregnation electrolytic solution with which the electrode wound body is impregnated, and a non-impregnation electrolytic solution with which the electrode wound body is not impregnated. The non-impregnation electrolytic solution includes a dinitrile compound. A ratio of a weight of the dinitrile compound included in the non-impregnation electrolytic solution to a total area of the positive electrode active material layer covering the positive electrode current collector is within a range from 2.00 μg/cm2 to 25.00 μg/cm2 both inclusive.
