Title:
タイヤ状態検出装置
Document Type and Number:
Japanese Patent JP6534634
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress lowering of a transmission function of a data signal.SOLUTION: A tire state detection device 20 includes a case 21. A pressure sensor 31, a transmission circuit 32, a transmission antenna 51, and a substrate 33 on which these are mounted are stored in the case 21. The substrate 33 includes: an insulation substrate 34; a wiring pattern 35 which is provided on one surface or both surfaces of the insulation substrate 34; and a resist 36. The wiring pattern 35 includes a substrate side antenna terminal 37 on which the transmission antenna 51 is mounted. An antenna terminal 54 of the transmission antenna 51 and a substrate side antenna terminal 37 are oppositely arranged via the resist 36. For this reason, the transmission antenna 51 is connected to the wiring pattern 35 in an electrostatic capacity coupling manner.SELECTED DRAWING: Figure 2
