Abstract: A connector including: a conductive portion that is brought into pressure contact with a bus bar and is electrically connected to the bus bar when the bus bar is inserted into an inserted portion; and a pressing portion configured to be displaceable to a first position and a second position, and receives a force acting from the bus bar when the bus bar is inserted into the inserted portion, is displaced from the first position to the second position, and presses the conductive portion at the time of the displacement to elastically deform at least a part of the conductive portion, in which the conductive portion is configured to cause, when pressed by the pressing portion and elastically deformed, an elastic force generated with the elastic deformation to act on the bus bar to increase a contact pressure with respect to the bus bar.

Abstract: There is provided a noise filter. A noise filter according to the present disclosure includes: a non-divided type magnetic core in which a through-hole having a first opening and a second opening at respective ends of the through-hole is formed; a conductive coupling terminal including a first connection portion and a second connection portion at respective ends of the conductive coupling terminal, the first connection portion and the second connection portion being connectable to busbars, the conductive coupling terminal being disposed inside the through-hole; and a holding portion that holds the coupling terminal disposed inside the through-hole. The coupling terminal is held to the magnetic core by the holding portion in a state where the first connection portion faces the first opening from inside of the through-hole and the second connection portion faces the second opening from inside of the through-hole.

Abstract: In a magnetic shield material including a magnetic layer containing a magnetic material and an electrically conductive layer containing an electrically conductive material, the electrically conductive layer is designed to have a thickness corresponding to a frequency band of electromagnetic wave to be shielded. More specifically, the thickness of the electrically conductive layer (thickness of the aluminum foil in the drawing) is designed to have a thickness to maximize magnetic field shield effect of the magnetic shield material (thickness of the aluminum foil corresponding to peak value frequency in curve E in the drawing) in a frequency band of electromagnetic wave to be shielded. This makes it possible to obtain good magnetic field shield effect of the magnetic shield material in the frequency band of electromagnetic wave to be shielded.

Abstract: To provide a sticking apparatus capable of suppressing turning-up of an end of a sticking body. A sticking apparatus extrudes a sticking body from a tip in a protruding direction of a head member while moving the tip in a protruding direction of the head member along a target range, and sticks the sticking body to the target range. Extrusion speed of the sticking body becomes smaller than movement speed of the head member from a start of sticking of the sticking body with respect to the target range to a first time point, extrusion speed of the sticking body becomes larger than movement speed of the head member from the first time point to a second time point, and extrusion speed of the sticking body becomes smaller than movement speed of the head member from the second time point to sticking completion of the sticking body with respect to the target range.
