[Problem] To provide a lightweight fiber-reinforced plastic product with excellent mechanical strength. [Solution] Provided is a method for producing a fiber-reinforced plastic product containing fibers and resin, the method comprising an additive manufacturing technology step, a first pressurization step, and a second pressurization step, the second pressurization step being a step in which a product obtained through the first pressurization step is pressurized under heating to obtain a product with its volume smaller than that of the product obtained through the first pressurization step.

Provided is a light-weight fishing gear item with high mechanical strength. This fishing gear item is a fishing line guide of which a body part is composed of a fiber-containing resin composition, the body part having a rib.
Provided is a method for producing, efficiently and in a short amount of time, a fiber-reinforced resin article having excellent mechanical properties. This method comprises: a 3D printing step in which a 3D printer uses fibers and a resin to build a shape; and a pressurization step for pressurizing the 3D printed product built by the 3D printing step. The pressurization step is performed at a temperature at which the resin included in the 3D printed product remains soft, and heat added to the temperature at which the resin remains soft comes from induction heat.

Proposed is a holding tool which has a flexural modulus of 50 GPa or greater in a circumferential direction, and which satisfies the property of having warpage of 0.5 mm or less. The holding tool is formed using carbon fiber and resin, has a substantially annular shape, and is provided with a first resin layer. In the first resin layer, the longitudinal direction of the fiber follows along the circumferential direction of the substantially annular shape.

A ceiling pendant (2) which is attached to a ceiling (1) so as to be suspended therefrom and which is used to install various kinds of devices in such a manner that the devices are spaced from the floor. The ceiling pendant (2) is provided with a horizontal arm (4) having a horizontal component, and the horizontal arm is a tube body consisting of a carbon fiber-reinforced resin and having an elliptic cross-section. Forming the horizontal arm as the elliptically cross-sectioned tube body consisting of the carbon fiber-reinforced resin makes the ceiling pendant lightweight, less likely to deflect, and less likely to be adversely affected by vibration.
