PROBLEM TO BE SOLVED: To prevent an antenna part of an antenna pattern from being exfoliated from a substrate, as further as possible.SOLUTION: A chip antenna 1 includes: an antenna pattern 3 that is formed by folding a conductive plate in a three-dimensional shape; and a substrate 2 in a hexahedron shape which is formed by injection molding with a resin while inserting the antenna pattern 3 and with which the antenna pattern is held on a surface. The antenna pattern 3 includes: a substantially rectangular antenna part 31 that is held on a top face of the substrate 2; and a plurality of terminal parts 32 which are held on a bottom face of the substrate 2 and disposed along a long side of the antenna part 31. Each of the terminal parts 32 is soldered on a circuit board 10. The antenna pattern 3 further includes a belt-shaped protrusion 34 that extends in a long side direction of the antenna part 31 and is embedded within the substrate 2. The protrusion 34 is provided along at least a range excluding the range in which the terminal parts 32 are disposed, in two long sides of the antenna part 31. |
