Abstract: A circuit connection device having one or a plurality of terminals, circuit board, tubular case body, terminal inserting portion and insulating first and second retainers. The terminal(s) are electrically connected to the circuit board. The case body accommodates the circuit board and has an opening at its one end. The terminal inserting portion has one or a plurality of penetration holes and closes the opening of the case body. The first and second retainers are accommodated in the case body. The terminal(s) are inserted into the penetration hole(s). The first retainer has terminal retaining portion retaining terminal(s). The second retainer has a positioning portion maintaining a position relationship with the circuit board, and is engaged with the first retainer. The first and second retainers are configured so that movement of the terminal(s) is restrained and the terminal(s) are connected to the circuit board.

Abstract: A circuit connection device for connecting circuit to an electronic device having one or a plurality of first terminals, circuit board, tubular case body, terminal inserting portion, terminal core and guide. The first terminal is electrically connected to circuit board. The case body accommodates circuit board and has an opening at its one end. The terminal inserting portion has a penetration hole and closes an opening of the case body. The terminal core is placed in case body. The guide is configured to guide the terminal core in an axis direction of the case body. The first terminal is inserted into the penetration hole of the terminal inserting portion. The terminal core has one or a plurality of second terminals electrically connected to the circuit board and insulating retainer retaining the second terminal. The retainer has a positioning portion that maintains a position relationship with circuit board.

Abstract: A method for producing a resin joined body in which a specific region L1 of a welding portion of a second resin member (21) is provided to form a low-laser-light-transmissible portion, and the low-laser-light-transmissible portion has a laser light transmissibility lower than that of a region of the welding portion other than the specific region L1. Welding is carried out so that a portion between points S2 and F2, serving as a weld overlap portion (112), is present in the specific region L1 forming the low-laser-light-transmissible portion. Also disclosed is a resin joined body.

Abstract: A resin member with a gas permeable member (8) includes a resin member having at least one gas hole (20h) extending therethrough between a front surface (8a) and a back surface (8b), and a sheet-like gas permeable member (50) covering the gas hole. An outer circumferential portion (50p) of the gas permeable member is embedded in the resin member. The resin member further includes first recesses (22) disposed around the gas hole, depressed from at least one of the front surface and back surfaces, and allowing at least a portion of the gas permeable member to be visible in a front-back direction, and second recesses (24) disposed externally of an outer peripheral edge (50e) of the gas permeable member and depressed from at least one of the front surface and the back surface and through which the gas permeable member is invisible in the front-back direction.
