PROBLEM TO BE SOLVED: To obtain a manufacturing method of a fiber-reinforced resin material molding in which continuity of reinforced fiber at crossed parts of crossing walls is secured and strength and elasticity modulus are improved even in the case where a high elasticity and long-fiber material is used.SOLUTION: A manufacturing method of a housing according to the present invention comprises: a first insertion process in which lower X-direction tabular substrate parts 9 each having a length exceeding crossed parts are inserted into X-direction grooves 12, and lower Y-direction tabular substrate parts 10 each having a length between adjacent crossed parts are inserted into Y-direction grooves 13; and a second insertion process in which upper Y-direction tabular substrate parts 15 each having a length exceeding crossed parts are inserted into the Y-direction grooves 13 after the first process to allow end surfaces thereof to contact with end surfaces of the lower Y-direction tabular substrate parts 10, and upper X-direction tabular substrate parts 14 each having a length between adjacent crossed parts are inserted into the X-direction grooves 12 to allow end surfaces thereof to contact with end surfaces of the lower X-direction tabular substrate parts 9. |
