DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described.
This will be described with reference to the drawings. FIG. 1 shows a circuit board 1 for a camera.
The connection terminal portion 11 formed on the end face of FIG. The connection terminal portion 11 will be described. First, a wiring pattern 11a is formed on the front and back surfaces of a plate on which a plurality of camera circuit boards can be formed.
A through hole 11b is formed at the center of 1a with a drill or the like. Next, a conductive member, for example, a copper paste 11c is embedded in the through hole 11b. Thereafter, the board is cut so as to pass through the center of the through-hole 11b to produce a plurality of camera circuit boards. Since the copper paste 11c is embedded in the through hole 11b, the cut surface becomes a flat surface. Thereafter, the wiring pattern 1 on the front and back surfaces
A gold plating layer 11d is formed on the surface of 1a and the copper paste 11c to form a connection terminal portion 11. As described above, the connection terminal portion 11 of the present invention is formed on the end surface of the camera circuit board 1 so as to be aligned with a flat surface without forming a concave portion.

As shown in FIG. 2, connection terminal portions 11 as described above are arranged on four end surfaces of the camera circuit board 1, and a concave portion 1a for accommodating the image pickup device 2 is provided on the upper surface.
Is formed. At the center of the upper surface of the image pickup device 2 housed in the concave portion 1a, a light receiving section 2a is located.
The terminal portion (not shown) and the connection terminal portion 11 are wire-bonded using the wire 2b shown in FIG. Holes 1 b and 1 c for fixing the optical device unit 3 are provided at diagonal corners of the circuit board 1. The hole 1c is formed as a long hole slightly longer in the direction along the diagonal line so that a slight dimensional error can be absorbed.

[0007] As shown in FIG.
Is for holding an optical device such as a lens 32 and the like. The lens holder 31 holds the lens 32 and the lens holder 31
The concave portion 33a of the lens presser 33 is fitted into the connecting piece 31a protruding upward from the upper surface of the lens presser 33, and is engaged with each other, thereby pressing the lens 32 undetachably. Lens holder 33

A groove 34c is provided at the bottom of the holder 34, and an adhesive 3 for fixing the holder 34 to the camera circuit board.
6 is poured and fixed. Further, a protrusion 34d that fits into the holes 1b and 1c is provided at the bottom of the holder 34. This constitutes a camera unit.

The circuit board 5 for portable equipment is provided with a socket portion 5a into which the circuit board 1 for camera can be fitted. On the inner surface of the socket portion 5a, there is provided a terminal portion (not shown) which is brought into contact with and electrically connected to the connection terminal portion 11 provided on the end surface of the camera circuit board 1. In a state where the circuit board 1 is fitted into the socket section 5a and the connection terminal section 11 and the terminal section conduct, the direction of the conduction is the plane direction of the board, and the thickness direction of the board as in the conventional case described above.
