Publication number: 20240096551Abstract: A method of manufacturing an inductor component includes preparing an insulating paste that is photosensitive and that includes a filler material composed of quartz, a glass material and a resin material, and a conductive paste, forming a first insulating layer by applying the insulating paste, and exposing the first insulating layer in a state where a first portion of the first insulating layer is shielded by a mask. The method further includes removing the first portion of the first insulating layer to form a groove at a position corresponding to the first portion, applying the conductive paste in the groove to form a coil conductor layer in the groove, and applying the insulating paste on the first insulating layer and the coil conductor layer to form a second insulating layer.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Applicant: Murata Manufacturing Co., Ltd.Inventors: Yoshiyuki OOTA, Tomohiro KIDO, Tomonori SAKATA, Masahiro KUBOTA, Kenta KONDO

Publication number: 20200027637Abstract: An inductor component comprising an element body formed by laminating a plurality of insulating layers, and a helically wound coil disposed in the element body. The insulating layer contains a base material and a crystal, wherein a refractive index of each of the base material and the crystal is 1.8 or less for at least one wavelength of 350 nm or more and 450 nm or less (i.e., from 350 nm to 450 nm). The coil includes a coil wiring wound along a plane, and the coil wiring is made up of one coil conductor layer or a plurality of coil conductor layers laminated in surface contact with each other. Also, the aspect ratio of the coil conductor layer is 1.0 or more.Type: ApplicationFiled: July 2, 2019Publication date: January 23, 2020Applicant: Murata Manufacturing Co., Ltd.Inventors: Rikiya SANO, Tomonori SAKATA

Patent number: 10294145Abstract: A coating composition contains 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a first resin composition, 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a second resin composition, and 40 parts by mass or more and 65 parts by mass or less (i.e., 40 to 65) of an inorganic powder. The first resin composition is a poly(meth)acrylate with a glass transition temperature Tg of ??20° C., and the second resin composition is a compound having structures represented by general formulae (1) and (2), below, one or more structures for each. R1, in general formula (1), and R2, in general formula (2), are each independently a hydrogen atom or a methyl group. X, in general formula (2), is any substituent that is not a hydrogen atom.Type: GrantFiled: January 11, 2018Date of Patent: May 21, 2019Assignee: Murata Manufacturing Co., Ltd.Inventor: Tomonori Sakata
