Problems solved by technology
[0010] However, in the joining member described in Patent Document 1, even if a well-shaped structure made of a metal material is to be further formed by electrolytic plating to form a part formed of a metal material, it is difficult to form a large part such as exceeding several tens of mm.
And, under the situation of joining the metal member that forms separately for the well-shaped structure made of metal material, the well-shaped structure made of resin material is packed in the gap of the well-shaped structure made of above-mentioned metal material, Therefore, deterioration of the resin due to heat, etc. are generated, so it is difficult to join by welding
Therefore, it is necessary to use a joining method that does not rely on welding, such as a joint based on threads, to join the well-shaped structure and the metal member, which may cause problems such as complicated structure of the joint part or difficulty in obtaining sufficient joint strength.

Embodiment Construction
[0140] Hereinafter, some embodiments of the present invention will be described with reference to the drawings. However, dimensions, materials, shapes, relative arrangements, and the like of components described as embodiments or shown in the drawings are not intended to limit the scope of the present invention, but are merely illustrative examples.
[0141] For example, expressions such as "in a certain direction", "along a certain direction", "parallel", "orthogonal", "center", "concentric" or "coaxial", etc. indicate relative or absolute configurations Not only strictly means such an arrangement, but also means a state of being relatively displaced by an angle or a distance to the extent that a tolerance or the same function can be obtained.
[0142] For example, expressions such as "same", "equal", and "homogeneous" that indicate the state of equality of things not only strictly represent the state of equality, but also represent the state of difference in the degree of to...

The invention provides a bonding member and a bonding member manufacturing method, wherein one objective of the present invention is to secure a bonding strength of a bonding member obtained by bonding a metal material and a resin material. The bonding member according to an embodiment includes: a metal member including a first base portion made of metal and a first engagement portion made of metal and provided integrally with the first base portion; and a resin member including a second base portion made of resin and a second engagement portion made of resin and provided integrally with the second base portion so as to engage with the first engagement portion. The first engagement portion includes a three-dimensional structure formed by a frame to form a plurality of cavities communicating with each other inside the frame, and the second engagement portion includes a resin filled in the plurality of cavities of the three-dimensional structure. A ratio of the frame per unit volume including the cavity and the frame in the first engagement portion gradually increases toward the first base portion while fluctuating.
Description
technical field [0001] The present disclosure relates to a joint member and a method of manufacturing the joint member. Background technique [0002] For example, a joining member obtained by joining a metal material and a resin material can be used in various applications as a material having both the characteristics of metal and the characteristics of resin. In such a joining member of a metal material and a resin material, it is necessary to join dissimilar materials such as metal and resin with sufficient joint strength. [0003] However, the adhesive strength at the joint interface between the metal and the resin may decrease due to, for example, oxidation of the metal due to the influence of moisture present at the joint interface. [0004] Therefore, in order not to rely on the bonding strength at the bonding interface of metal and resin to ensure the bonding strength of the metal material and the resin material, it is considered that the resin material and the metal...
